Hm, the module probably wasn't built with a high enough debug level by
default.  It's alright, we'll come back to that if we need to.

Not sure what's up with the hang yet, however, I noticed the issue [1]
which is likely causing the error messages from nouveau's i2c code.
With some luck, it'll stop triggering whatever bug is making it hang in
the VBIOS init table parser.

Ben.
