I have exactly the same symptoms with 2:2.8.0-2, I'm afraid. If I boot
with the screen attached, xrandr works exactly as I would expect it to
(and as it works on my more modern intel-powered laptop). If I boot
without the screen attached, xrandr works exactly as I would expect
except that nothing is ever displayed on the screen.

(Sorry for the delay: the affected machine is semi-retired, and doesn't
have a screen anywhere near it.)
