Fixed it, so it's one of those two reverted commits which broke it between 2.6.34 and 2.6.35.9.

Upstream fix will be something like this: http://kyle.fedorapeople.org/hda_realtek-handle-unset-external-amp-bits.patch
OK, fixed in the next 2.6.35/2.6.36 builds, and Takashi has queued the fix upstream. Thanks for testing.
