Hello everybody

I fixed a few bugs in COMPAT_DARWIN and added a few traps, and now both
XDarwin and WindowServer fail on mapping some video related memory. 

XDarwin wants to map something called kIOFBSystemAperture, and
WindowServer wants something called kIOFBVRAMMemory.

Anyone with deeper knowledge of video chips have an idea of what they
are exactly?

We want to get some on-screen display. The easier way I can think about
is to map the OpenFirmware framebuffer, is it reasonable?

And how can it be done? Any OF expert here?
