I have the problem too - but I am having on a IIci. Actually
I think that the comment earlier about the logic board
being the thing that is going south may be right. Last night,
I left my mac on, and the heat in my office went almost off. 
This morning my office was about 60 deg. Still in operating
range supposedly, but my mouse then acted really fried. I could
not get it to move right hardly at all.

I recently started using Maxima - a product that lets the MAC see
more than 8Meg of memory (while i wait on 7.0...:-(  ). That
about dates the time that I started having this mouse problem.
This is a shot in the dark... but anyone else have BOTH mouse
trouble AND use Maxima?
