The issue was fixed upstream.
The commit that fixed it:
http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?h=linux-3.17&id=6fbb702e27d78ad2458df048b58cca3454bc0965
I tried the ubuntu-utopic kernel with the commit on top, and it works fine
again.
HDMI gives signal again, no more errors in dmesg, and suspend/shutdown also
works.
Guess this is a must-have!
