this patch and others like it are obviously just to keep Linux
in sync with ACPICA to minimize the diff we must track.

But there is actually quite a bit in ACPICA that is not in Linux.
The most useful, from a debugging point of view, might be the
hooking the ACPICA debug code into the kernel debugger --
something that Luming did about 2 years ago.  However, as the
debugger was not part of the Linux kernel tree, the changes
didn't really have a good path to a customer...
