Is there anyone currently working on the ACPI code?  The laptop[0] I've been
using recently doen't support APM at all, and having suspend would be nice.

That being said, I've poked at the code a bit, mainly by cribbing from the
FreeBSD 5 tree, and http://people.su.se/~lha/patches/netbsd/acpi-wakeup-1

It looks like S1 suspend will "Just Work" since the hardware takes care of
everything.  Laptop doen't implement that though so I can't test it. :/

S3 suspend needs the acpi-wakeup-1 patch, slightly modified wakeup code,
and lots and lots of new powerhooks.  With those changes it half works
though[1].

The diff contains:
 * acpi-wakeup-1
 * VBIOS reset on resume
 * /dev/apmctl interface glue code. (So I can use apm -d -z to test)
 * if_rtk_pci powerhook.
 * if_iwi powerhook. (Card still doen't work after resume, but no longer
   causes a hard lockup.)

I'm probably going to poke at this till I get it working on my box, something
is missing/busted in the cbb powerhook, and the agp code needs a hook to save
the PCI config space.

Thoughts?
