Subject: intelfb refuses to load

Hi!

I'm trying to fix up my kernel setup so that X is happy... currently
it fails to start with:

FATAL: Could not load /lib/modules/2.6.37-rc5+/modules.dep: No such
file or directory
(EE) intel(0): No kernel modesetting driver detected.
(EE) Screen(s) found, but none have a usable configuration.

So far I have:

CONFIG_DRM=y
# CONFIG_DRM_TDFX is not set
# CONFIG_DRM_R128 is not set
# CONFIG_DRM_RADEON is not set
# CONFIG_DRM_I810 is not set
# CONFIG_DRM_MGA is not set
# CONFIG_DRM_SIS is not set
# CONFIG_DRM_VIA is not set
# CONFIG_DRM_SAVAGE is not set
# CONFIG_STUB_POULSBO is not set
CONFIG_VGASTATE=y
CONFIG_VIDEO_OUTPUT_CONTROL=y
CONFIG_FB=y
CONFIG_FB_I810=y
# CONFIG_FB_I810_GTF is not set
# CONFIG_FB_LE80578 is not set
CONFIG_FB_INTEL=y
CONFIG_FB_INTEL_DEBUG=y
CONFIG_FB_INTEL_I2C=y
# CONFIG_FB_MATROX is not set

And on the command line:

BOOT_IMAGE=(hd0,2)/l/linux-good/arch/i386/boot/bzImage root=/dev/sda4
resume=/dev/sda1 psmouse.psmouse_proto=imps psmouse_proto=imps
psmouse.proto=imps vga=791 init=/tmp/swsusp-init
acpi_sleep=s3_bios,s3_mode no_console_suspend i915.modeset=1
video=intelfb:mode=1024x768 fbcon=scrollback:64k

...but intelfb fails with:

[drm] Initialized drm 1.1.0 20060810
intelfb: intelfb_init
intelfb: Framebuffer driver for Intel(R)
830M/845G/852GM/855GM/865G/915G/915GM/945G/945GM/945GME/965G/965GM

intelfb: Cannot reserve FB region.
intelfb: cleanup

Any hints? If I'm doing some trivial mistake, perhaps "cannot reserve
FB region" message could be improved?
