F15, Intel, External display(s) only - anyone?

I'm trying to determine if this combination is viable:

* Lenovo T520 with Sandy Bridge GPU
* Fedora 15 (or 16) 32-bit
* External display as only display

Is this working for anyone?  I'm considering tagging this BZ for 
inclusion in the CommonBugs wiki area since there seem to be a lot of 
reports that look similar (see my comment [1] to this effect).

If this is working for you, did you do anything special?  I am right now 
unable to use Fedora 15 to boot my system in an external-display-only 
mode without signficant fooling around at runtime (switching modes, 
etc).  Additionally, once the system puts the external display to sleep 
(which seems to happen after at most 1 hour, no way to disable this), it 
will never return until I start mode switching again.

I'm very frustrated but trying to DoTheRightThing here and make sure 
enough info is provided on the right BZs.  Alas, not much traction.

Thoughts?
