Bug#398948: intelfb not working
I'm having simular problems.
I've tried booting with parameters like:
video:intelfb:mode=1024x768-8@70
But it never seems to be loading the intelfb module.
When I modprobe it, I always get this:
intelfb: Framebuffer driver for Intel(R) 830M/845G/852GM/855GM/865G/915G/915GM/945G/945GM chipsets
intelfb: Version 0.9.4
intelfb: 00:02.0: Intel(R) 830M, aperture size 128MB, stolen memory 892kB
intelfb: Non-CRT device is enabled ( DVO port A ). Disabling mode switching.
intelfb: Video mode must be programmed at boot time.
And it's not creating a /dev/fb0 at that time.
The "Video mode must be programmed at boot time" also doesn't seem
to match the documentation or the rest of this bug report.
I'm trying this with a 2.6.23/24 kernel.
