Debian Unstable 2.6.12.2 kernel

I shutdown my machine last night and now the keyboard and mouse do not work when I boot it back up, in Debian only, Windows works, so does boot onto a LiveCD. There were no problems using the mouse/keyboard the night before, and there are no errors, that I can see in

/var/log/messages X
/var/log/Xorg.0.log
/var/log/gdm
/var/log/dmesg
~/.xsession-errors

I am connecting to the machine using a Cybex 4 port switch, however plugging a keyboard and mouse directly into the machine doesn't work either. Arch 0.7 had the same problem too.

I've googled around but could only find hits to do with keyboard/mouses not working from the start, where mine did.

Has anyone got any suggestions/links/google search words
