Okay, after one of the most time-consuming git bisects ever, I think
I've found it:

0b1076c4b2a06e517fafbb2b4704f23e69b05386 is the first bad commit
commit 0b1076c4b2a06e517fafbb2b4704f23e69b05386
Author: Julian Andres Klode <[email protected]>
Date: Tue Sep 27 19:00:48 2011 +0200

staging: nvec: Introduce new internal API for msg alloc/free

Introduce two new functions nvec_msg_alloc() and nvec_msg_free()
that allocate and free message buffers from the internal pool
of messages.

Since you guys have probably forgotten about this since it took so long,
I'll recap:

While watching video with mplayer, the nouveau driver crashes rendering
X totally non-responsive, though the system still behaves normally via
ssh or serial console. Dmesg attached, and I've cc'ed the author of the
first bad commit.
