I bult Xorg on iMc, Radeon HD 4850 with ddvd support and "starts"

This is a know issue: our current console implementation, "syscons",
doesn't know about KMS (the new way to driver video cards from the
kernel, not from X.Org itself). Therefore, once you start X.Org, the
console can't use the display anymore, neither during your X session
using Ctrl-Alt-Fx, nor after you exit from X.Org.
However, even if your screen is blank after X exit, the computer doesn't
crash and can be used remotely. This also means you don't have to force
a shutdown: a short press on the power button will shut down the
computer properly.
it should be possible for the vga driver to issue a vga reset to the
device..
I believe there was a standard reset instruction in the original VGA
design.
Every device since hten should have copied it. even if they disagree
about everything else.
