I've gone ahead and updated to the latest nightly:

Linux rnavarro-thinkpad 3.13.0-994-generic #201401100405 SMP Fri Jan
10 09:05:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

The release done on 1/10/14

I'm still getting the underruns, they're actually a bit more frequent
now. Right after I logged in I got one one my second monitor, and then
shortly after another on my first.

The latest log can be found here (01-10-2014 drm-intel-nightly):
