The DirectFB driver for this card (intelfb) complains about the video mode not being set even though I've set it using the kernel parameters passed through grub:
title Generic 2.6.21 with 945GM-21
root (hd0,0)
kernel /bzImage945-21 root=/dev/hda3 video=intelfb:mode=1024x768-16@85,accel=1,hwcursor=1,vram=8
The parameters above are listed in the kernel's fb documentation (Documentation/fb/intelfb.txt). Does anyone know why this is happening or how to fix it?
Agp Info:

intelfb: Non-CRT device is enabled ( LVDS port ). Disabling mode switching.
intelfb: Video mode must be programmed at boot time.
intelfb: cleanup
When I try this with a CRT instead of an LCD screen the kernel crashes before I can see anything.
