I have: Enable modesetting on intel by default (DRM_I915_KMS) not set

not then I will test those patches out.

Could you test the patches without switching to KMS first? Otherwise,
the underlying bugs aren't going to get fixed for anyone else...

Thanks a who lot for that.. machine wakes up perfectly with that patch..

dmesg of a patch applied with a good wakeup:

only really thing now I am seeing is:
[drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking
[ 146.362007] render error detected, EIR: 0x00000010
[ 146.362007] page table error

but might just be cosmetic.
