Ah, could you recommend what we should be using?  Jake was just
following the directions on http://lhms.sourceforge.net/howtouse.html
which suggested those were the patches to use.

Are there plans to make all systems use one approach or the other, or
will there always be several ways to access it?  (So we can account for
them when designing the testsuite.)

Also, we haven't started looking at x386/x86_64 yet, but will they use
ACPI or probes?

Thanks,
