hey dotan -

this has been a common problem for a long time.  the most commonly used
solution appears to be to force the kernel to use a particular mouse
protocol.  for me, it worked to add this to the grub.conf line for the
kernel:  psmouse.proto=imps

others have found other protocols.

but, i have never had any problems with the xp box getting confused, so
you may have some other problem going on.
