Improvements:
* /etc/rc.suspend,rc.resume are always run, no matter the source of the
suspend request (user or kernel, apm or acpi)
* suspend now requires positive user acknowledgement. If a user program
wants to cancel the suspend, they can. If one of the user programs
hangs or doesn't respond within 10 seconds, the system suspends anyway.
* /dev/apm is clonable, allowing multiple listeners for suspend events.
In the future, xorg-server can use this to be informed about suspend
even if there are other listeners (i.e. apmd).
Changes:
* Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE. Request begins the
process of suspending by notifying all listeners. acpi is monitored by
devd(8) and /dev/apm listener(s) are also counted. Users register their
approval or disapproval via Ack. If anyone disapproves, suspend is vetoed.
* Old user programs or kernel modules that used SETSLPSTATE continue to
work. A message is printed once that this interface is deprecated.
* acpiconf gains the -k flag to ack the suspend request. This flag is
undocumented on purpose since it's only used by /etc/rc.suspend. It is
not intended to be a permanent change and will be removed once a better
power API is implemented.
* S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z.
This restores previous behavior of halt/shutdown -p being the interface.
* Miscellaneous improvements to error reporting

Since we can only override the DSDT, a custom ASL dumped previously that

now include the contents if any SSDT table as well. This makes use
of the property that one can concatenate the body of SSDT tables to
the DSDT, updating the DSDT header (length and checksum) and end up
with a larger and valid DSDT table. Hence, this also works with -f.

What is the HPET I hear you ask? It is the High Precision Event Timer
that is supposed to supplement and eventually replace the 8254 timer and
the RTC periodic interrupts. Among other things, it is 64 bit (can be
run in 32 bit mode for 32 bit cpus), and is suitable as a replacement for
the ACPI timer on SMP systems (the specs are much better) and as a
replacement for the ITC based synthetic clock for on ia64 systems.
It seems IA64 and AMD64 systems tend to have this. It is likely to start
showing up in i386 systems if it isn't already on some of them.
