Hi Daniel,

just wanted to test the fb-fix [2] from Alan and followed the thread in [1].
Me is also working with i915 KMS.

I looked at nouveau KMS driver and adapted the part for i915:

drivers/gpu/drm/nouveau/nouveau_drm.c-200-      /* remove conflicting
drivers (vesafb, efifb etc) */
drivers/gpu/drm/nouveau/nouveau_drm.c:201:      aper = alloc_apertures(3);
drivers/gpu/drm/nouveau/nouveau_drm.c-202-      if (!aper)
drivers/gpu/drm/nouveau/nouveau_drm.c-203-              return -ENOMEM;

Untested by me, feel free to test.

Maybe some of the i915 and/or fb driver experts can comment on the problem.

Regards,
- Sedat -
