Actually after doing a diff on atkbd, there don't seem to be any differences between 2.6.9-rc1 and 2.6.8.1. :( Also after looking back through my logs some things worth noting here:

These have been here for a while.

Looking at the messages above, it appears to me that this is being detected as an AT keyboard (or default) instead of a PS/2. Could this be a problem?
