I've been able to boot and test with 2.6.37-rc1-00170-gf6614b7
- and this problem seems to be fixed in this version (vt.c file seems
to be gone?).

With kernel 2.6.37-rc1-00170-gf6614b7  message has changed (with
enabled polling thread)
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm:i915_reset] *ERROR* GPU hanging too fast, declaring wedged!
[drm:i915_reset] *ERROR* Failed to reset chip.
X[1378]: segfault at 0 ip 00007f33409c727d sp 00007fff930e7120 error 4
in intel_drv.so[7f3340990000+4a000]
[drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero.

But I can't be sure about whether it's the same bug - as display seems
to be enabled for a second after resume.
and then just everything crashes.. - with original EIR bug 19052 - my
display remains completely black

I'm  using Fedora Rawhide  Xorg & driver:
