What happens if you just drop the 0x126 next to the 0x124 in
engine/device/gm100.c ?

I don't know of anyone with the hw... maybe Ben got one? If you're
interested in helping, the kernel logs from the above experiment + an
mmiotrace of the blob drivers (see
https://wiki.ubuntu.com/X/MMIOTracing) + vbios (see
http://nouveau.freedesktop.org/wiki/DumpingVideoBios/).

I assume you're on a recent kernel? You need 3.19 for the GM204 stuff
to work in the first place.
