After upgrading to 2.6.28, any Nvidia drivers == CRASH

Question

I finally did an update to my system, and now with 2.6.28, No matter which nvidia drivers I use, things work fine in Xorg for an indeterminent amount of time, then all the sudden, my screens blank and the box is completely unresponsive to ping.  At this point, touching the keyboard causes beeps.  Presumably the kernel has paniced.
I've tried nvidia-180.29-3, nvidia-173xx (173.14.17-2) nvidia-96xx(96.43.11-2) as well as getting nvidia drivers directly from nvidia's site, doing an uninstall through here, etc.  I know the issue is related to nvidia, since when I switch to vesa, the problem goes away.
Interestingly, the crash always seems to happen as a result of me typing on the keyboard.  For example, I will be using mutt in an mrxvt terminal, and as soon as I hit 'j' or 'backspace' the box crashes.  It never crashes when just using the mouse or not as the result of typing.  Of course, this only happens after around 30 minutes or so, as I am using this setup right now and typing is working fine.
Presumably the rest of the Arch community isn't hitting this or it would have been addressed by now.  My device is:

Actually I was wrong, this isn't a kernel panic, and may not even be related to Nvidia.
Xorg just plain crashes, and it does seem to be in keyboard handling code:

Where can I get symbols to debug this?  Or is there way to just run Xorg inside gdb from the start?
