The common approach seems to be to provide /proc/apm -- even on machines
with a PMU we do that. Many ARM machines do likewise, etc. 

Yes, that kernel<->user interface isn't ideal, and if you start using
ACPI the lack of consistency sucks because it doesn't follow that
defacto standard -- but that's a separate issue, and is no excuse for
actually using AML crap instead of proper drivers.
