Are there any drivers that support the "X" modes (like 360x480x256) but
map the video contiguously to 0xD0000000?  I've been playing around
with et4000x.grn and it seems that if you write directly to screen RAM
it doesn't work.  (It does work if you use GRPlotNC, though.)

Alternatively, perhaps someone could describe the way that video RAM
*is* mapped, so I could adjust my VGA mode 13 drawing routines accordingly?

Thanks,
