Hmm.... Oh, lovely - so we have that non-zero if set, 0 if it's i386 or
amd64 and not set and not defined if it's ia64 and not set.

Sigh... It should be left as #if, of course, but I suspect that cleaner way to
deal with that would be (in Kconfig)

config ACPI_BLACKLIST_YEAR
int "Disable ACPI for systems before Jan 1st this year" if X86
default 0
