> 1) use a different 1280x800 mode at runtime

Didn't work.

> 2) hard code panel size in nv_crtc.c

Worked!

In case it's useful, here's what the driver had calculated for the offending
values:

 adjusted_mode->HSyncStart - 75 -1 = 0x578

 adjusted_mode->VTotal - 5 - 1 = 0x326

> 3) change a flag register in nv_crtc.c

Err, wrong button :)

That one produced an artistic combination of black alternating vertical lines
and a vertically stretched image (we could only see the top 1/3 of the screen
on the panel).
