--- Comment #38 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Same as before, but now with:

8e9e3d2deacc460fbb8a4691140318f6e85e6891 + hdmi-1.patch + hdminva3.patch +
hdminva3-4.patch

BTW, do make sure that you're booting the right kernels/installing modules (I
assume nouveau is a module in your case). In case you weren't doing that, and
this patch works, please go back and re-test the various patch versions.

If this doesn't work, I think the next logical move is to run mmiotrace on a
working kernel and the above patched up kernel, and compare the traces to see
what it is that we're messing up. I think that the old logic accidentally read
random garbage off the stack and wrote it to registers, so perhaps that random
garbage happened to be correct.
