acpica-unix 20110527 imported

[Sepherosa Ziehau]

Hi all,

acpica-unix 20110527 has been imported into master.  Since it requires
almost no serious changes in the OS support code, it probably will not
cause as much trouble as the last import.  If you have any problems w/
it, please let me know.

Major work import is done by Magliano Andrea (randy), thank him very much :)

Best Regards,
sephe
