As Dan points out many laptops are forced to use APM at least on some
distros. Also, I know several people who use APM because suspend doesn't
work using ACPI but it works nicely with APM. So it's pretty important
to support I think.

I just changed pretty heavily how non-sysfs things like ACPI, PMU and
APM are handled, so I added something roughly based on this. I removed
the polling code for now; we should probably listen to /dev/apm_bios
for changes in an addon; dunno yet.

Btw, I just added the generic Rescan() and Reprobe() discussed earlier
(which, btw forced me to do the heavy change mentioned above) so the addon
should just invoke Rescan() on the appropriate hal device object to
force a re-read of values. For playing around, you may use something
like this python script

 #!/usr/bin/python
 import dbus
 bus = dbus.Bus (dbus.Bus.TYPE_SYSTEM)
 hal_service = bus.get_service ('org.freedesktop.Hal')
 d = hal_service.get_object ('/org/freedesktop/Hal/devices/apm_0', 'org.freedesktop.Hal.Device')
 d.Rescan()
 d = hal_service.get_object ('/org/freedesktop/Hal/devices/apm_1',
'org.freedesktop.Hal.Device')
 d.Rescan()

to force a rescan. You need to be root (or haldaemon user) for this to
work.

Cheers,
David
