Useful when we don't know which subsystem is failing.

This is really unnecessary unless I'm missing something.  You can pass nouveau.debug=LEVEL (without specifying a subdev name) to set the default already.

Why make default 0400? 0600 or 0644 would make more sense..

Does not work for me: http://bpaste.net/show/45252/
(ignore gpio debugging messages - I'm looking for suspend regression)
