PATCH - acpi 0619

[Nate Lawson]

I've prepared a new diff of the 0619 drop of acpica along with the
appropriate changes to support code:

* Use ACPI_BUFFER as the type for AcpiGetObjectInfo
* Remove AcpiEnableEvent/AcpiClearEvent for ACPI_EVENT_FIXED (power/sleep
buttons) as they are no longer needed
* Change calls to use the new GPE functions
* Add AcpiOs*Lock functions
* Import 0619 + local FreeBSD changes + dsmthdat.c patch (from
kochi at netbsd.org)

Please test and let me know how this works for you.  It works fine on my
IBM T23.
