Kernel modules: nvidia, nvidiafb

That's bad twice, you shouldn't load the blob and nvidiafb.

Maarten, I think those modules got loaded because I passed vga=795 option to
the kernel. I'm using vanilla kernel and nvidia blob wasn't installed.
Well I
removed vga=795, modprobe -r nvidiafb, and I still get the blank screen. When
ssh'ing to the machine dmesg seems to get overflowed with:

Perhaps the unconditional enabling of many hotplug irq's has turned on a
"bad"
one.

Short time bypass would to be to not enable them, ~line 130 in
linux-core/nv50_display.c

Long term solution requires mapping all the irq bits, assuming that it is
indeed the problem.

On a different note, besides the existing 0xe050/0xe054 registers, a fairly
similar 0xe070/0xe074 has appeared, perhaps just on g9x cards?

I'll leave Ben to decide.
