Hi Ed,

yes, I do load mousedev as well as psmouse in /etc/modules due to udev
no longer loading it. my problem, however, is _not_ that teh module
doesn't get loaded. It's the mouse pointer jumping all over the screen.
After some time (inactivity?) it calms down and is usable. Then, after
some minutes it again jumps wild all over the place, seems to click
stuff on it's own, and again calms down, ...

This problem shouldn't be udev related.

One note: the pointer seems to be in love with the corners of the
screen. It always goes there when it goes wild... ;)
