Richard -

Yes, "DLL04B0" is the same device. Several thoughts:

* Do you get ANY errors/warnings when building the psmouse.ko dlkm?
* What does "modprobe -v" report? It should be something like
"/lib/modules/3.2.0-30-generic/updates/dkms/psmouse.ko"
* What OS and ver are your running?
* Can you boot up into an Vista/Win7 or run a powerup diagnostic to
confirm it's not a hardware issue?
* Eyeball the crash stack trace and look for any paths through a
psmouse* or alps* function call. Each will have a hex offset. Email me
what you see.
