Sure. I develop it there. :)

I was reimplementing an old halt.com that I lost the source to. I
started in 8086 assembly (apmoff.asm), and then decided to add ACPI
support for some systems where APM doesn't work.

But doing it in assembly is a nightmare, so I moved to com32. And
porting the APM version to it was the first step (apmoff.c). :)

I'd rather have a full shutdown.c with APM and ACPI version, but it will
take me some time to digest the ACPI spec.

So, yes, APM is ready, ACPI will follow (hopefully).
