Dual-head Matrox, monitors at different resolutions?

[mlg 3 <m_l_g3@yahoo.com>]

I have managed to configure dualhead mode on my
matrox G550 under debian (BTW, I had to upgrade to 
the 4.1 driver), but there's still a problem:

One monitor is TFT (Sony SDM-X93), 
and the other is CRT (SUN Microsystems GDM-5410).
The video mode 1280x1024 at 60Hz is what the TFT LCD
monitor is supposed to do,
but having the CRT monitor in the same mode makes
a very poor sight.

It looks like something (the driver?) prefers 
to have both monitors in the same mode.

Question:
Have someone managed to configure a matrox to use
two different monitors at two different screen 
resolutions and refresh frequencies?

If yes, can you please post your XF86Config-4 file(s)?
What version of the driver do you use?

(Theoretical answers "this should be this way" also
will be appreciated. But the following change
(see what's commented out) changes nothing:
both monitors go to 1280x1024 at 60 Hz.
