apparently it is set:
40: 00 01 00 5f 00 00 00 00 ff ff ff ff 00 00 00 00

If I modporbe it without setting it, the bit keeps set:
40: 21 4f 09 df 00 3c 00 00 06 ff ff 06 00 00 00 00

after manually setting it to 0 and modprobing matroxfb it kept the zero:
40: 21 4e 09 df 00 3c 00 00 10 ff ff 10 00 00 00 00

but the crash still occured.

I can't notice any delay when it passes the second time.
