PS/2 mouse support broken in 2.6.0-test9

[Aaron Grewell]

Hey all,
I just had an interesting go-round with my newly-upgraded workstation. 
I installed 2.6.0-test9 and found my mouse was behaving very strangely. 
It jumped around the screen a lot, and the mousewheel was inoperative. 
Nothing had changed except the kernel, so I dug into Google a bit and
then reconfigured my kernel.  Everything is now fine, but you may find
this interesting.  It appears that the new input layer in 2.6.x has
broken existing PS/2 mouse setups.  My mouse is actually USB, but since
I had 'legacy USB support' enabled in BIOS and had compiled the PS/2
mouse driver into the kernel it was using the PS/2 driver.  In order to
return my mouse to normal I had to remove PS/2 and the USB Boot Protocol
drivers from my kernel, replacing them with the Full HID and HID Input
Layer drivers.  I also compiled in the USB and UHCI drivers (rather than
using modules), which fixed my no-usb-keyboard-on-softboot problems.

So if you should happen to play with the new kernel, I recommend a USB
mouse.  Hopefully they'll fix this before long, but you wanted a new
mouse anyway, right? ;)
