   This makes use of some macros that are only defined for i386/x86_64,
so the ia64 build fails on piix4acpi.c.  However, I'm not sure why these
are x86 only, and the cset that made them x86 only doesn't appear to
have any dependency on them.  Things seem to work fine if we enable
these for everyone.  Thanks,

        Alex
