Near as I can figure, it's not the VGABIOS that's screwing up, but the Bochs VBE code. Big-endian X11 works. -DG

There seems to be a major incompatibility between the Bochs VBE code
and its Carbon GUI code. This is evident because when Bochs is compiled
for Apple X11 under MacOSX, both Apple Darwin-x86 and the debian-woody
image are able to display in VBE mode, but neither can when Bochs is
compiled for Carbon. It seems that redrawing simply stops, but I don't
quite see what in the code is making it stop. I know that carbon.cc
needs a lot of work, but I think this is release-critical, and the
problem may also exist in other GUIs. RSVP with your feedback. -DG

The graphics display code is okay for VBE in X11 (linux on i386), SDL (linux
and win32), wxWindows (linux and win32) and win32. I have no access to
big-endian machines, so I cannot test this version of the X11 gui. The Carbon
gui (and some others) should be able to display VBE 8 bpp modes. Graphics
modes with >8bpp should cause a panic.
