I suspect the kernel is having fun with interrupts, but not enough
information to make a diagnosis.

Title:
[gm45] maverick screen does not update except when mouse moves or key
is held down
Status in “xserver-xorg-video-intel” package in Ubuntu:
Incomplete
Bug description:
[Workaround]
Use a 2.6.36 kernel. e.g.:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36-maverick/
Binary package hint: xorg
The screen does update very reluctantly unless I move the mouse. This
can be seen very well e.g. in sytem monitor resources. The graphs move
smoothly as long as I wiggle the mouse, if I stop the graphs only
update in fits and bounds. This does not happen always, but the system
has gotten into this state rather regularly for as long as I have been
trying maverick afair. The system also leaves this buggy state by
itself. Often within a couple of minutes. CPU and IO load are normal
at all times.
