The beginnings of one can be found in my "FreeBSD and WaveLan"
document. I've attached part of it (note that I haven't had the time to
incorporate information from the recent PCI adapter saga).

TROUBLESHOOTING
1. Nothing appears to happen after rebooting.
Run dmesg. Look for lines that start with "pcic0:". If you find
some, the PCMCIA adapter was found, and you should skip to the next
item.
If you can't find any, this probably means that there is a problem
with the PCMCIA adapter/controller:
* Are you running FreeBSD 4.0-RELEASE or 4.0-STABLE older than May
29, 2000, and did you just reboot from Windows 95/98/NT? Older
versions of FreeBSD 4.X have a minor bug where the PCMCIA
controller is not recognized if you just rebooted from Windows.
This bug was fixed in 4.0-STABLE on May 28, 2000.
If you reboot again, the PCMCIA controller should be found.
Basically, if you were running Windows, you need to reboot twice
-- or turn off the power -- to get FreeBSD to recognize the
adapter.
* Is the PCMCIA adapter port address correct? Note that the default
address of the WaveLan PCMCIA adapter is 0x3E2, but the default
for the FreeBSD driver is 0x3E0. They've got to match.
2. The ISA PCMCIA adapter does not recognize the WaveLan card; nothing
happens when the card is inserted.
If you assigned an IRQ to the ISA PCMCIA adapter (recommended), did
you tell the BIOS that this IRQ is not available for use by PNP/PCI
cards (see step #2 in the configuration section, above)? One
indication that you didn't do this is an IRQ mismatch, like:
pcic0: <VLSI 82C146> at port 0x3e0 iomem 0xd0000 irq 10 on isa0
pcic0: management irq 11
Note the IRQ mismatch (10 vs 11). If this is configured properly,
the IRQ values should match, like:
pcic0: <VLSI 82C146> at port 0x3e0 iomem 0xd0000 irq 10 on isa0
pcic0: management irq 10
3. The PCMCIA adapter does not recognize the WaveLan card; you get
error messages like:
pccardd: No card in database for ""("")
This particular error is usually caused by a memory address
conflict; if so, the solution is to set "iomem" to a different
address (see step #9 in the configuration section, above). To
verify a memory conflict, try running "pccard dumpcis"; if you get
messages like "code XXX ignored", where "XXX" is a number, then you
probably have a memory conflict.
If you changed iomem, did you also edit /etc/rc.conf to reflect that
fact? The values for iomem and pccard_mem in /etc/rc.conf must
match. If you edit rc.conf, you'll have to reboot.
If the memory addresses are correct (iomem and pccard_mem), "pccard
dumpcis" should output a section like (in addition to a lot of other
text):
Tuple #4, code = 0x15 (Version 1 info), length = 80
000: 05 00 4c 75 63 65 6e 74 20 54 65 63 68 6e 6f 6c

Addit. info = [Version 01.01],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[]
Note that the above is approximate; it may change with different
card firmware revisions.
4. Did you edit /etc/pccard.conf to allow the use of IRQ9 for the
WaveLan card (wi0)? IRQ9 may not work with the WaveLan card. You
may have to come up with another IRQ.
5. The WaveLan driver complains about:
wi0: No irq?!
This means that the driver could not allocate a free IRQ for the
WaveLan card. Unfortunately, there's no easy solution for this --
you've got to somehow free up an IRQ for the card. Note that the
list of possible IRQs to use is listed in /etc/pccard.conf; if you
free up an IRQ, make sure it's listed there.
6. The driver complains about:
wi0: No I/O space?!
This means that the driver could not allocate a range of I/O ports
to use to access the card.
I've only seen this when I tried to insert the WaveLan card into a
laptop that already has another PCMCIA card in another slot, and the
wi0 driver failed because it could not allocate an IRQ ("wi0: No irq?!").
If I ejected the other card and re-inserted the WaveLan card, I
would then get the "No I/O space?!" error. The solution is to
reboot.
(I think this is caused by a minor bug in the pccard or wi driver
code.)
