DDC Detection ausschalten

[HyperY2K]

Ich bastel jetzt schon ne Weile an folgender Konfiguration:
-Ubuntu OS mit ATI-Grafikkarte Radeon9000

Ich möchte, dass zwei "Desktops" laufen (1 per VGA und 1 per TV Out)
und das Ganze mit versch. Auflösungen.
Mit angehängter xorg.conf klappt das auch, solange der VGA-Monitor verbunden ist. Ziehe ich ihn ab und starte das OS wird nur ein "Desktop" geladen, d.h. 1 Desktop wird über TV ausgegeben.
Hat jemand eine Idee, wie das Ganze auch ohne angeschlossen Monitor funktioniert?
