Two things may be going on here:
  1) we're setting the DP audio enable bit too early I think; we should only set it when we go to a normal link mode
  2) there may not be enough bw for audio at 25x16 with the clock configuration we use, we may need to reduce the audio config somehow

Paulo, do you have a DP monitor you can test with to confirm?

I just confirmed that 25x16 works fine on my ILK laptop with drm-intel-next-queued, but I don't have any audio in my config.

Martin, it would be good if you could re-test with drm-intel-next-queued too, just to rule out recent fixes (there have been a number that might affect this).
