This gets reset by something in /etc/rc.sysinit. It happened
to me eons ago before I started using the method mentioned
below.

I happen to have a Matrox G550 and in RH9 used
append="video=matrox:vesa:447" in my /etc/lilo.conf.
While using the 2.6-test kernels, this changed to
'video=matroxfb:vesa:447' in grub.conf. I now use
vga=791 in FC Test 3 and have tried vga=447, vga=0x1BF
and video=matrox:vesa:447 to no avail. I want to run
my monitor at 1600x1200 at 32bpp or 24bpp. I'd really
appreciate any help I can get for the correct parameter
to pass to grub.

TIA
