Hello Roychris,

on 2.4.25-rc1 the i8042_nomux=1 option causes the following:
- on a single read on /proc/apm the mouse still jumps
- several/few reads make the mouse to stop and only to work after a few 
seconds
- a fast endless read makes the mouse to stop at all and never work again

Commenting out the lines in 2.6.2-rc2 causes the mouse not to work at all. No 
error messages, nothing in the logs.

Do you have a Thinkpad R31 and it workes there for you?

Thanks a lot for your help,
	Bernd
