It might be worth having a look at /proc/interrupts to check that the
count for 4 goes up when you move the mouse, and the count for 3 when
you talk to the modem (keeping the mouse stationary).
Does this only happen in X? Have you got the right mouse selected?
Is gpm still running on the consoles when X is running? If so,
are you using the -R method of running the X mouse? This may be
worth trying.
Just some suggestions to try out.
Cheers,
