FC5: video resolution problem

[starcycle at gmail.com]

when i boot normally, i can only get a max. resolution of 800x600 at
16 depth. when i add vga=775 to the grub kernel line, i can boot to my
LCD max resolution 1280x1024, but i lose the direct rendering. my card
is a matrox G450 and i have a samsung 172t LCD, but i'm using the
generic LCD option which seems to be working. has anyone seen this, or
have any suggestions?

thank u,
s.c.
