OK, replying to myself here....

It appears that the intel driver fails to reset and/or initialize my 
hardware correctly.

With a TV connected, the hardware detects the TV exactly 1/2 the time.  
Every other time X starts, the monitor is detected correctly.  The other 
time it is not.

Clearly something is wrong with either my hardware or the driver, or both...

Here's a snippet of the log file:

And here's the next time:

This is 100% repeatable.

I'm attaching the files with debugging turned on.  Is there anything 
else I can do at this point to help solve this?  I'd like to be able to 
force the output on; I know it's connected.  This is for a kiosk and it 
has to be 100% reliable....
