odd.  it would be interesting to see the output of
	aux/realemu
	monitor=vesa aux/vga -p | grep mode

the most likely issues is either aux/vga has incorrectly parsed
some modes and gotten the wrong bit pattern, or the vesa bios
is wrong.  it might be worth trying the resolution you want with
different bit depths.  x8 or x32 might be worth a shot.
