Hold button on headset does not report events.

hexdump -C /dev/input/event0

Jack insertion/removal, aux-button pressing produce events as expected.
Hold button on headset does not.

Verified by me, and two others on #openmoko.

I can't see anything clearly wrong with the kernel patches in this area.
If gpio.txt is accurate, it seems connected to the correct IO.

The HOLD button only works when MICBIAS is enabled, which only happens when the
amp is powered up. There's not much to be done about this since it is a
"feature" of the hardware design.

I verified it by using DM2 headset test and hexdumping /dev/input/event0, it can
probably also be confirmed by setting "Mic Sidetone Mux" to "Mic2" in alsamixer
while hexdumping (worked here but not sure what other settings have to be
enabled there).

I'm closing as WORKSFORME but unless you know this little foible of course it
doesn't work for me or anyone else.
