To add auto detection/automatic driver setup for a frame grabber board which has a custom Linux driver. I've managed to get kudzu to add the following line:

alias char-major-81 itifg

to /etc/modules.conf

However, after loading the module I get

cat /proc/devices
Character devices:
[ ... ]
254 itifg

In other words the module registers itself with major id. 254, while I would assume 81 from the modules.conf entry. Any ideas why? How exactly does kudzu determine device ids?
I think I know why this device id is used now: It's simply because the board is identified as a CAPTURE class device, and 81 is the official id for video4linux/"Video capture/overlay" devices.

I'm still not quite sure what to do in order to get automatic setup of my device, though. I could change the major id. of the driver, I guess, but I'm not sure if that would be right.
