Minor correction to what I wrote earlier about the scroll wheel. That is 
actually my mouse. It says Dell but it's really made by Logitech.

I just tried the console and what's funny is Favorites actually works as 
Capslock and Previous works as right-shift. X has the opposite problem.

In case anyone missed it, Debian Stable works fine with this keyboard. 
The keyboard on the working Stable machine is exactly the same (same usb 
id's). I'm not familiar with the input stack, but in case it is a kernel 
problem, the difference is:

Stable dist, working:
Linux zero 2.6.26-2-amd64 #1 SMP Thu Sep 16 15:56:38 UTC 2010 x86_64 
GNU/Linux

Testing dist, not working:
Linux tom 2.6.32-5-amd64 #1 SMP Fri Sep 17 21:50:19 UTC 2010 x86_64 
GNU/Linux
