@Ton van Vliet:

See #20 for a "by hand" patch for the actual problem - thanks to Frank
Larimer for identifying it there.

This or an equivalent made it into 10.10's kernel as described in my
#22, so 10.10 is the lazy option if you want to upgrade.  [Do I read it
right: The MS compiler generates code with malformed addresses that are
supposed to be 32-bit by the spec, while MS Windows cheerfully ignores
upper 16 bits?  Or is this something the author of the DSDT has to
directly screw up, and Windows' behavior just lets them get away with
it?]

re: 10.10 on these systems, the unrelated noise from the other bug
mentioned in my #22 is actually more intermittent/not nearly so much of
an issue or annoyance as I first thought, if it's not already fixed
anyway [haven't checked since 10.10 went final, it may have been fixed
by now].

Importing or enabling the "N,000 messages: Ignoring" feature as found in
certain BSDs might not be a bad idea, still...
