* Do you get ANY errors/warnings when building the psmouse.ko dlkm?

No errors or warnings. The build works fine.

* What does "modprobe -v" report? It should be something like
"/lib/modules/3.2.0-30-generic/updates/dkms/psmouse.ko"

When I do the "modprobe -v psmouse" the crash happens. It happens immediately, and if there is any response from the modprobe command I can't see it. I tried sending it to a file with 1> and 2> to get stdout and errout, but no files were created.
.
* What OS and ver are your running?

I am on Ubuntu 12.10 beta 64 bit. Here is the result of a uname-a:
Linux rbmlaptop 3.5.0-14-generic #19-Ubuntu SMP Fri Sep 14 20:21:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

* Can you boot up into an Vista/Win7 or run a powerup diagnostic to
confirm it's not a hardware issue?

I don't have either installed--I am several years past the "I might need Windows for something" phase of switching to Linux so I just get rid of it--but I will try to find some diagnostics to run and report back if I can.

* 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.

The stack trace is the same as the images posted above in #174. I will take some photos and get you some offsets next time I try this.

I may also try to install it on an earlier kernel and see if that makes a difference. Given midhat's similar experience, I think it might be related to the newer kernel and not hardware.
