Ok, first question, where did you get mga_vid from ?

Sounds wierd.

No, it should be just within the memory range of the card that
lspci reports.

udev would not cause something like this. I rather supect that
the wrong memory range got overwritten.

What i need from you is:
1) mplayer -v log
2) the messages mga_vid writes to klog (see dmesg)
3) what mga_vid version you use and where you got it from
