Here's a "me too" for resume troubles in 2.6.28, MacBook Core Duo with i915
graphics. I'm about a week behind in my git tree though.
Probably unrelated, but in testing other stuff I noticed that 2.6.27.3 worked
whereas 2.6.27.4 does not. Reverting "ACPI Suspend: Enable ACPI during resume
if SCI_EN is not set" makes it work there. In 2.6.28-rc3, reverting the same
commit met with mixed success:
* resuming from X got me one successful resume after a long timeout,
and one resume with mouse-pointer-only
* resuming from console always worked
With the above mentioned commit, resume never worked.
