Ok, I've gone through a full buildworld/buildkernel with acpica-unix-20040527
and did a few tests and it seems to be working. The patch is based on
the update20040617 plus some cleanups. Anyway, the patch is here:

http://les.ath.cx/DragonFly/acpi-update-3.patch.gz

There are a few things to note:
- default value for disable_on_poweroff has been changed to 0, so you may
  have to add the following line in /etc/sysctl.conf
    hw.acpi.disable_on_poweroff=0
- new code no longer compiles with acpica-unix-20031203, because of some
  new symbols added in the later ACPI-CA code. I initially tried to
  cope with it by making both old and new codes conditionally-compiled
  (using SYSACPICA_VERSION), but I gave up because the code became ugly.
  it still compiles with acpica-unix-20040514.
