Hi i have a big problem trying to configure X server

ok so first my debconf doesn't work anymore
dpkg-reconfigure xserver-xfree86
just gives me a blue screen (What ??? a blue screen on linux ? )

i have a matrox card and before debconf screwed it self i could make X work.
In the configuration with debconf i said i wanted to use mga.
The log complains it failed to load mga_hal (module does not exist)

i try to do updatedb && llocate mga_hal to check if it's around on my system and it's not.
No matter how i compile the kernel mga_hal doesn't seem to exist.

Does anybody have an idea ?

Thanx
