Hello list,
here is a report about my experiments with a "Matrox Mystique" in
a C200. The attached diff shows the _temporary_ changes I made to the
matroxfb.
I replaced the {read,write}{b,w,l} calls to their __raw equivalents,
because Petr Vandrovec told me that matroxfb expects them to do BE to
PCI on BE machines. I had no success when running the card in LE mode.
After modprobing the module with noinit=0 the frame buffer seems to be
up and working. I can use fbset on the device and display text by
writing to /dev/tty1. But as soon as there is much traffic (like ping
-f through a NIC or disk i/o) on the PCI bus, the kernel hangs.
testing was done with 2.4.19-pa17
This is the output of PIM after doing a TOC:

I suspect that there's something wrong with the pci bus, but I couldn't
decode it further.
here is the log from modprobing the module:
