Hmm.  I did find this site:

http://www.ece.utexas.edu/~jlang/linux-keyboard/

which has a patch for 2.4.18.  I tried the patch with 2.4.20, and the
USB keyboard and mouse didn't work at all, even though they were
getting detected by the hotplug usb.agent.  Good thing I had a PS/2
keyboard nearby.

I spent a lot of time playing with this, I saw the keybdev and
mousedev modules getting loaded, and I simply could not figure out why
they were not getting input from the keyboard and mouse themselves.

Well, are you getting keycodes above 255?  If so, you're probably
using a kernel newer than 2.4.18, which is stock with RH 8.0.  2.4.18
won't recognize 256 or higher for a keycode according to the source.
If you could let me know your kernel rev, that would be great.

Thanks!
