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).

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.

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).
