Bug#318231: Console gets garbled when starting X

[Svante Signell <svante.signell@telia.com>]

Package: xserver-xorg
Vsrsion: 6.8.2.dfsg.1-2 
Severity: Serious

The console screen gets completely garbled when starting X.org. 
Going back to the console C-A-{F1-F6} or exiting X gives the same
result. X works fine, also with C-A-Fx to C-A-F7. The font seems to be
black with a black background. The mouse prompter and the cursor is
white and visible. The console has a blue frame all around the screen.
stty sane does not work. 

I have upgraded from 4.3.0.dfsg.1-14. The old configuration file ir
reused: XF86Config-4 was copied and renamed by the install to xorg.conf.

Graphics card is MGA G400 with driver mga.
