Wow, great work!  I only skimmed through your patch, and I do have
some comments, but this is awesome.  I don't have access to any
displayport monitors here to try that stuff myself, but I'll look over
your patch as soon as I can, though perhaps others already have/will.
I'll try to scavenge some equipment at work.

Prost,
qwx
