OK, like this ? :

I've used 'text' on the kernel command line to prevent gdm from starting. Then
typed this :

sudo rmmod radeon
sudo rmmod ttm
sudo rmmod drm

to make sure the driver is not loaded (it was not).

started it :
sudo modprobe agpgart radeon

and started gdm :

sudo /etc/init.d/gdm start

Sadly this does not help much. I tried this with the 1920x1200 screen, which
was recognized correctly. So that's good :) However I failed to get it to work
at 1920x1200.
Need a little more help.
