I recently switched from the proprietary driver to the nouveau driver
and everything appeared to go well except that during boot I see:
GPU lockup detected switching to software fbcon
so I did some googling and ended up adding 'nouveau.noaccel=1' to my
command line which solves the issue. Obviously this isn't ideal as I'd
like to have accel turned on ;)

Does anyone have any idea why I'm getting the lockup?

dmesg (with noaccel option) , kernel config, and lspci output
attached. In my googling I did see one mention of someone w/ this gpu
lockup problem and it seemed to be caused by having more than one
video device. My mobo does have an onboard graphic device, but I've
disabled it in the BIOS and it does *not* show up in the lspci output,
fwiw.

I do find it a bit odd that there is no mention of nvidia/nouveau in
the 'eselect mesa' output above, but I don't know if that is normal
since 'eix mesa' shows that it does see my video choice:
