As far as I can tell from my recent experiences the black screen means that the ATI r128 drivers uses the VGA output instead of the builtin CRT. I speculate that this is a PC inheritance. The VGA output is well hidden under a hatch at the back, on my 400 MHz grape iMac DV at least, so I attached a VGA screen there. The X output nicelly appeared on the VGA screen only.The framebuffer driver used before X is up outputs console on both outputs. Unfortunality a bug:
