Matrox G450 problems with 2.4.0 and xfree
Dear Petr,
I think I might have something to add to this discussion, but then
again you probably know this already!

Installed a Matrox G450 on my linux system. Now it has problems booting. The kernel is compiled with framebuffer support so is supposed to boot up with the Linux logo. Unfortunately the systems hangs when the kernel switches to the graphics mode. When I first boot into windoze and the reboot to linux it works fine. So it looks like an initialisation problem...

Windows drivers works around somehow, as after booting to Windows matroxfb works fine - but without Windows it is just pure luck.
I have a similar problem to the one outlined above with kernel 2.4.x
(hardware details below).
I don't have Windows installed on my machine, but I find that if I
cold boot to 2.2 (RH7) first and start up X (4.0.2 with Matrox driver 1.00.04 compiled in), I am then able to "shutdown -r now" and warm restart to 2.4 with FB acceleration enabled. This generally works fine
for me.
The 2.2 kernel I have (2.2.16 Redhat 7.0 standard) does not have FB
enabled
This isn't generally too much of a problem because 2.4.x is so
stable
I don't have to reboot for weeks!

It looks like that if you compile 'agpgart' into kernel, chances that it will work are better, but I have also reports that it did not changed anything.
I have agpgart compiled directly in (not as a module) to the kernel,
but this does not seem to relieve any of the cold boot problems :-(
I'm willing to try out some patches if that would be useful.
