After finding the missing bit poweroff works now.

I cleaned up the patch and moved most of the dsdt.dsl and
acpi_tables.c into the southbrige/northbridge directory.
Updated patch should fix abuild error and incorporates suggestions
on irc by uwe (thanks for the comments).
Thanks to Idwer Vollering <vidwer@gmail.com> for the original patch.

Tested:
  Linux (poweroff, powerbutton event)
  XP (poweroff, powerbutton event)

Abuild-tested
