Found a possible workarround:

http://www.thinkwiki.org/wiki/Installing_Ubuntu_6.06.1_on_a_ThinkPad_R60e#Using_xrandr_with_Ubuntu_7.10
"If you see the 'TV disconnected' line but have neither TV connector nor docking station (eg Thinkpad R60e) then add to the Monitor and Device sections of xorg.conf as noted above. This will prevent the external (VGA) flashing off for a few seconds every time xrandr is used. (Newer versions of the intel driver may fix this.)"

Basicly, you have to set xorg to ignore the tv-out.
Don't tested it.
