I now run a VGA console kernel without agpgart with a 16bps X.
So, there seems to be two issues:
- broken matrox fb: I lose the synchro when switching from X to fb. fbset configuration is lost when switching consoles.It is feature, not a bug. fbset does not work on 2.6.x kernels anymore. Apply ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/matroxfb-2.6.0-t3-c1149.gz if you prefer 2.4.x behavior.

In fact, it works untill I switch to another console... What is the right way to change the console configuration at run-time, now ? Or where should I look for this info ?
Did it become impossible (would be a severe bug, at least for me...) ?
"stty cols XXX rows YYY" sets size. How you'll set pixclock, color depth or other features is unknown to me - I use my patch above and others should ask James Simmons...

Also if you are using DRI, even latest XFree mga driver I found still reprograms hardware even if XFree server is not on a foreground, so you must use same color depth and vxres for both X and console, and even in this configuration display corruption on console may occur from time to time...

OK, you confirm exactly the symptom I have seen.
So it seems to be an X driver problem...
But X is still buggy when it doesn't use DRI,
at least in 32 bits modes. I know it's quite certain that it's an X bug, but I really would like to understand why it works with 2.4 kernels and not with 2.6 ones. The X problem is there even if I use the VGA console (I mean with a kernel with fb support _not_ activated).
In 2.4.x kernels dri refused to work on couple of systems I have, while in 2.6.x it is willing to work even on more systems - if we are talking about console.
I do not know why you have problems with X - 2.6.0-test3-bk-current works for me with G200, G450 and G550 with Debian's unstable XFree, (16/16bpp on G550 system and 24/32bpp on others).
