Correct.

Yes.

That's the problem. There may already be one in there, in which case
you may need to do nothing. I can't see anything in there with the
name Canon, but the card doesn't have to have the Canon name. A
typical entry might be like this:
# Non-brand Compact Flash Card(32MB)
card " " "KCF 32M"
config 0x1 "ata" ?
If your card isn't recognized, you'll get messages like this in the
/var/log/messages:
Nov 28 12:25:45 sydney /kernel: pccard: card inserted, slot 1
Nov 28 12:25:51 sydney pccardd[3279]: Card "CL ATA FLASH CARD LEXAR "("TIDALWV") [V1.01] [(null)] has function ID 4
Nov 28 12:25:56 sydney pccardd[3279]: driver allocation failed for (null)((null)): Device not configured
In a case like this, you might create a new entry:
card "CL ATA FLASH CARD LEXAR " "TIDALWV"
config 0x1 "ata" ?
This might still fail because of irq conflicts. You can specify a
particular irq in place of the ?, for example 9 in this case:
card "CL ATA FLASH CARD LEXAR " "TIDALWV"
config 0x1 "ata" 9
Now you should get:
Nov 28 12:29:50 sydney pccardd[3286]: Card "CL ATA FLASH CARD LEXAR "("TIDALWV") [V1.01] [(null)] matched "CL ATA FLASH CARD LEXAR " ("TIDALWV") [(null)] [(null)]
Nov 28 12:29:55 sydney /kernel: ata4 at port 0x260-0x26f irq 9 slot 1 on pccard1
Nov 28 12:30:05 sydney /kernel: ata4-slave: ata_command: timeout waiting for intr
Nov 28 12:30:05 sydney /kernel: ata4-slave: identify failed
Nov 28 12:30:05 sydney /kernel: ad8: 7MB <LEXAR ATA FLASH> [251/2/32] at ata4-master using BIOSPIO
Nov 28 12:30:05 sydney pccardd[3286]: ata4: CL ATA FLASH CARD LEXAR (TIDALWV) inserted.
The device you get depends on what you have configured in the system,
but will typically be at least device 4. In this case it's /dev/ad8.
Create device nodes:
# cd /dev
# ./MAKEDEV ad8s1
All compact flash cards I've seen have used slice 1, but you can use
fdisk to be sure. To mount the card,
# mkdir /camera
# mount -t msdos /dev/ad8s1 /camera
You can then use normal UNIX commands to manipulate the photos. Don't
forget to umount before removing the card.

You're getting younger all the time. Well, no older...
