I took the problem upstream as suggested (#74629 on
bugs.freedesktop.org).

Lennart Poettering suggested various things but we still have not
resolved the problem.

Meanwhile, I installed the Debian package "triggerhappy" which has a
daemon called "thd" which helped me diagnose the problem further.

The Sleep Key on AOD 270 seems to be generating an event on
/dev/input/event0 (Keyboard) and *no* event for the special Sleep Key
event device /dev/input/event3. This can be seen by running "thd --dump
/dev/input/event3".

It is not clear why this is so. Perhaps logind is "misinformed" by the
kernel that Sleep events are being generated on /dev/input/event3? Or
perhaps the kernel is not handling this particular laptop correctly.
(Using a standard Debian kernel here.)

Hope this helps in diagnosing the problem.

Regards,

Kapil.
