Grr. Did not pass through due to DUL blacklist...
What is DUL blacklist ?
If the problem is with my e-mail address (it is an hamradio address), you can use <[email protected]> instead.
No. Problem is with linux-kernel@... It started blacklisting direct mails from dialups, so I have to implement some workaround on my side (as I do not want to use provider's SMTP gateway - I do not trust them).

Can you try 'video=matrox:init' ? And 'video=matrox:nopan'?
Bingo ! 'init' does not work but 'nopam' give me a normal display without the fbset gimnick.
It looks like that there is some problem with screen offset computation then. Can you try 'video=matrox:cross4MB' instead of '...:nopan'? I did not have 8MB Mystique for testing, and it even looks reasonable - Mystique does not use WRAM memory, so there is no need for WRAM workarounds. If it will work, I'll cook twoliner for Linus.

Next step will be to test dual head. I've already installed an AGP ATI (S3 chipset) together with the PCI matrox Mystique and it seems to work. If I succeed, I will attach a normal VGA display on the ATI board and a 19" IBM (not multisync) on the Matrox. The ATI card is a cheap one with only 4Mb RAM. I've upgraded my Matrox Mystique to 8Mb, so I hope it will work.
Now, I will have a look on how to useXF68_FBDev(if needed).
XF4.0.x should work reasonably well. Or you can run accelerated XF on mga:
matroxfb is compatible with accelerated XF 3.3.x, and with accelerated XF 4.0.x WITHOUT enabled DRI (as DRI code reprograms hardware even if X are on background) (and 'Option "UseFBDev"' is required if you are using both heads of G400/G450 with XF4).
