I had the same problem and posted a patch for wd.c a few days ago to questions.
With your configuration (cdrom as master on the secondary port) this patch
should solve your problem.
The problem is that the probe in wd.c fails with only a cdrom-drive on the
2. port, probably not another port address.
Here is my original mail:
Last week I got my atapi-cdrom-drive and had some problems with
my FreesBSD-2.1R .
The kernel detected the drive only as slave on the IDE-port.
Unfortunately with this configuration (disk master, cdrom slave)
the disk transfer slows down by a factor of 2.
So I had a look into the source of wd.c and voila, a few changes to
wd.c made the cdrom-drive working on the second IDE-port as master drive !
Here is the patchfile (hopefully not only working for me) :

----- then do a "patch < wd.c.patch" and recompile the kernel -----------
This should also work in STABLE (the wd.c is the same as in Release)

This is the dmesg-output from my system with the patched wd.c:
...
