Another data point.... I see erratic mouse behavior occasionally myself,
same as you describe. Usually if I switch back and forth between X and Quake.

Tyan Tomcat III Dual p166mmx processors. I've seen this with nearly every
kernel I've ever ran (going wayyy back).

Ps/2 mouse, Xaccel 1.2 X server. I figured the ps/2 mouse stream was getting
interrupted mid-packet and things didn't recover. Maybe you're having an
interrupt problem that exacerbating this?

I'd love to see it go away... could the mouse driver sense a "change of stream
reader" and reinit the mouse? Or does that not make any sense at all...
