[ale] Wacky Mouse

[David Corbin]

I posted this yesterday to gentoo-user, but I've not gotten much response, and 
my laptop is largely unsusable, so I thought I'd ask here too.
-----
Today, my mouse has gone wacky. ?Previously I had a fine working Gentoo/X11 
system on my Dell I8600. ?A week ago, upgraded my profile, and updated the 
system, including switching to udev. I had no problem for the last week, so I 
believe that all worked well.

Today, I did another update ("emerge -uavD world"), and started to muck with 
user-mode linux. ?This did necessitate a rebuild of my kernel, and a reboot. ?
When I was done, my pointer is wacky.

"Wacky" mean the pointer is largely "stuck" near the bottom left corner of the ?
display. ? Any attempt to move it generates a great deal of flashing of the 
pointer. ?When I start X, the pointer appears dead center of the screen, 
until I touch the touchpad at which point it jumps to the bottom left area of 
the screen.

I've reviewed what was emerged, and I don't think anything is likely to have 
caused this problem. ?I've tried changing my config to not use the synaptics 
drive, but that had no effect.

Any ideas?
