Hadn't tried, but I obviously should have :
On server start (no output):
fred at minifunky:~$ xrandr
SZ: Pixels Physical Refresh
*0 800 x 600 ( 433mm x 271mm ) *60
1 640 x 480 ( 433mm x 271mm ) 60
2 1280 x 800 ( 433mm x 271mm ) 60
3 1280 x 768 ( 433mm x 271mm ) 60
4 1024 x 768 ( 433mm x 271mm ) 99 60
Current rotation - normal
Current reflection - none
Rotations possible - normal left inverted right
Reflections possible - none
None of the modes except the last one give me an output. But:
fred at minifunky:~$ xrandr -s 4
Excellent. Note that OS X seems to be able to generate output for other
resolutions, at least 800x600 (I haven't tried more, I've got to rush

If I can do anything to help you getting things right (except sending my
adapter :-)), just ask!
