After the latest upgrade (Rawhide Feb. 26) when I rebooted kudzu
reported that my mouse was removed and then added a mouse....all is 
fine except the added mouse was not the right device. I am not sure
how wide this problem is but it may worth taking care of:

I had a link /dev/mouse --> /dev/sgc which itself was a link to /dev/sg2

this was working until now....but now mouse is switched to /dev/psaux
(I am not sure who/what does this...not the kernel since that has not
changed...I am using my own 2.4.1 kernel).

So, device /dev/mouse was left undefined and starting scripts for gpm
and xf86 failed. The only way I could solve this was to delete /dev/sgc
and link /dev/mouse to /dev/psaux....if I did not delete /dev/sgc
kudzu kept showing that as the device!

FYI
