Current kernel message (using alsa-kernel, I'll clone and build your git
soon, got some internet problems at the moment):
[  147.334343] XXX HDMI pin_sense = 0x7fffffff
[  147.565059] XXX HDMI pin_sense = 0x7fffffff
[  153.248894] XXX HDMI pin_sense = 0xffffffff
[  153.250443] XXX HDMI pin_sense = 0xffffffff
[  189.475073] XXX HDMI pin_sense = 0x7fffffff
[  189.698017] XXX HDMI pin_sense = 0x7fffffff
[  196.664565] XXX HDMI pin_sense = 0xffffffff
[  196.666079] XXX HDMI pin_sense = 0xffffffff

It recognizes when I take the cable in and out, or toggles display output
(0xffffffff when connected).
