and i had a black screen.
After i add in the line boot : "agp=off vga=0x31b" via menu.lst like :
default=0
timeout=0
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.27.5-117.fc10.i686)
root (hd0,0)
kernel /vmlinuz-2.6.27.5-117.fc10.i686 ro root=UUID=009af6f1-a5a4-4475-a7c5-6138a8d0190e rhgb agp=off vga=0x318 quiet
initrd /initrd-2.6.27.5-117.fc10.i686.img
It is simply but it works for me and fine in 3d.
Sorry for my english language but i hope to help you.
