Thanks for testing.

Can you reproduce it with kernel-vanilla?

Sorry for the delays ....

On 11.4: kernel 2.6.38-rc3.3.1 vanilla exhibits the same behavior ("black
screen") as kernel desktop from kernel/HEAD.

Please note: in every case, lid closure/reopening immediately following "black"
screen will restore the dispaly in proper form, and boot continues.
Continuance to the DE login screen without the lid closure/reopening requires a
workspace switch:

close lid
reopen lid
ctrl+alt+f7 (<--- not always required)

Further, with each -rc3 kernel, power management enters a behavior loop during

recover (as above)
prompt for permission

Only method of recovery is re-boot.

I will test on 11.3 shortly and post back.

Note: The -rc3 kernel is definitely faster (over -rc2) during boot and in
subsequent activity.
