You can try enabling either of the debugging sections of apmd_proxy,
to see if the events are at least reaching the script.  My guess is
they are not.  APMD itself should definitely be passing those along,
and even logs them.

It is conceivable that the BIOS just isn't sending those events.
Which would be wierd since SONY/Phoenix obviously know how to do APM
already: my 505G works fine.

The ultimate test is to enable debugging in the kernel module, but
that requires a recompile.

In principle the power change event could be simulated by comparing
the succesive ac power-on values.  Currently apmd depends on a change
event from the BIOS.
