Sorry about previous bogus mail.

If I do so, it seems that radeon driver accepts it. xrandr:

I'm unable to make work an external monitor with experimental radeon
driver. I tried ModeLine + PreferredMode without luck. I tried the
following from the command line:
elacunza@elacunza:~$ xrandr --auto
xrandr: cannot find crtc for output VGA-0
elacunza@elacunza:~$ xrandr --output VGA-0 --mode "1440x900"
xrandr: cannot find crtc for output VGA-0

Monitor is conected, believe me! :)

Shall I test Virtual 3000 1600 with Xserver 1.4 as a last test?

Shall I fill-in other bugreports?
- experimental radeon problems with external monitor
- experimental radeonhd not auto-adding to layout mouse and keyboard sections

Thanks a lot!
