AMD's "Mystery" Digital Block Supported

So this doesn't help with the DVI scanline bug in any way if you already have DVI working?

Wow! It actually fixed it. All hail the Magical Mystery Block.

The issue here as I understand it is that the initial POST setup was pretty close and worked for many users, but adding the driver support (a) fixed some remaining issues, and (b) allowed the output to work even if a display was not connected at power-up (the POST only initializes connected outputs).
