Matroxfb behaves buggy

I tried both
MATROX_G450andMATROX_G100drivers, first G450 and then G100. I find it odd that both are configured, since selecting G450 hides G100 in "make menuconfig", so I have all the time assumed it is disabled when it's hidden. Might the problem be caused by including both? I'll go and see, but I think it's not the only problem.What's the difference between them? .config help ought to tell this briefly.
As far as I can tell, it is as clear as it could be... First option is named 'G100/G200/G400/G450/G550' support, while second is named 'G100/G200/G400'.

When 2.4.20 switches to 1280x1024, the screen goes black with 2.5.72, then some seconds pass and 1. vertical dark gray lines appear, and 2. some dark blue areas between them. Some seconds pass and X comes up as if nothing was wrong.
I logged in to the console as root, not seeing anything. The TFT display reported 640x480@60Hz in it's menu. I typed "fbset 1280x1024" for my custom 1280x1024@60Hz mode. Oddly, X display appeared at 1280x1024 resolution, mode parameters being something between the fbset and X modes, but I could do nothing, so I pushed the reset button.
fbset is not supported on 2.5.x kernels for setting console resolution. If you want same environment you had in 2.4.x, get patch from ftp://platan.vc.cvut.cz/pub/linux/matrox-latest.

syslog had a screenful of "^@^@^@^@^@^@^@^@^@^@^@" between time before the lockup and next boot, as did kern.log
No surprise... But I doubt that it is matroxfb's problem.
