FWIW, the SGI O2 has the same problem, I heard the Xorg server got
fixed recently to take this into account. I don't know if the fix is
O2 specific.

Btw, wouldn't it be the right thing to add a Sun framebuffer emulation
instead of fiddling with VGA? Or is the hardware in question actually
VGA compatible?
