This is a reissue of an earlier report, and I've since done some more digging.

Up to kernel 2.4.20-pre2 there was no problem, agpgart et al ran fine etc,
but from 2.4.20-pre4 onwards when Xwindows starts to load these modules
I am instantly thrown back to a booting machine.
The same kernels on a VIA MVP3 chipset box with a Matrox G200 are fine.

I have ascertained that any attempt to use agpgart triggers it.

Rather than clutter up the list with lots of log files, I've made a web page at
http://www.users.bigpond.com/allan.d/bug/Matrox.html
with all the info I could gather.

Any suggestions of how to improve the error messages around the failure point
are welcome.  Nothing is written into dmesg at the time of failure.
