[Intel-gfx] i915 KMS wrong resolution later on boot

[Carlos R. Mafra]

I have a laptop with 1280x800 and an external monitor with
1280x1024, and the end result after boot and entering X is
that I get both at the wrong resolution of 1024x768.
(after running xrandr I can fix the resolution)

The laptop has this card
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

and my kernel has

CONFIG_DRM_I915=y
CONFIG_DRM_I915_KMS=y

On 2.6.33-rc3+ (and previous kernels too) the KMS gets the
correct resolution in the beginning of the boot and later
sets it wrong. Grepping 'drm' from the dmesg shows me this:

[    1.988283] calling  drm_core_init+0x0/0x137 @ 1
[    1.988379] [drm] Initialized drm 1.1.0 20060810
[    1.988429] initcall drm_core_init+0x0/0x137 returned 0 after 95 usecs
[    1.995913] [drm] set up 7M of stolen space

[   31.845095] [drm] DAC-6: set mode  2b

and see how at ~2 secs the resolutions are correct and then at
~10 secs (when X is starting) they are wrong. Why does this happen?
I am using OpenSUSE 11.2 so my userspace is new.

The whole dmesg is here:
http://www.aei.mpg.de/~crmafra/dmesg-drm.txt

(my kernel has one btrfs patch and a i915 patch to keep the
outputs disabled after s2ram, http://lkml.org/lkml/2009/12/31/13
but the problem happens regardless)

Is there something else I can do to help solve this issue?
