I've the same problem with some simple P2 machine which started recently.
I was pretty sure it's a hardware problem, e.g. plugging unplugging mouse made
it go bad, so I didn't bother mailing the list.
It worked fine with 4.1-STABLE from mid-september I think.
It begins after some time, and power-cycling is needed to make it work.
The mouse begins acting like it's using different protocol - i.e. jumping all 
over the screen and selecting and pasting.
I use windowmaker there, but the problem exists in the terminal mode as well.
I need to check the cvs to see what was changed recently...
