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.
