If I start up in single user mode, I get only one console. No switch possible.
So I start in run-level 3.

If I run system-config-display in, saying tty1, it start successfully.
If I switch to tty2, then back to tty1, I don't see the system-config-display 
dialog any more, just the command I typed before.

Unfortunately, resolution is too low (320x200), so, I can't see the "Cancel" 
and "Valid" or "OK" button of the system-config-display dialog.

Unfortunately not.

Mouse is working.

I don't know if I can post such heavy files here...
This is a devel list, not a user one.
Xorg.0.log is 38Kb and messages is 435Kb !

VGA compatible controller: ATI Technologies Inc M71 [Mobility Radeon X2100] 
(rev ce) (prog-if 00 [VGA controller])

I think now it's a X server problem as it can't compute modelines for vga 
module. I get, in Xorg.0.log, many lines as:
(II) VGA(0): Not using default mode "320x240" (insufficient memory for mode)

Lines differs in mode value

(II) VGA(0): Not using default mode "1920x1200" (insufficient memory for mode)

I know that the 1920x1200 mode is doable.
