Does needs to be 1, but your loop script below shows it set (reverted?) 
to 0, so devd events would not be invoked.

Not without having dev.acpi_ibm.0.events=1 anyway.

Suggest also checking Beto's examples which might help you debug it:

http://lists.freebsd.org/mailman/htdig/freebsd-mobile/2006-August/008959.html

http://lists.freebsd.org/pipermail/freebsd-mobile/2006-August/008948.html

and which I notice executes scripts like:
      action "/bin/sh -c /home/betom/bin/do_acpi_suspend.sh";

which might help if your script wasn't set executable?  and uses
/usr/local/etc/devd for devd conf files, as an alternative.
