Thanks for the correction. I'll resend the earlier
s/LOCAL_APIC/IO_APIC/ patch then.

Just found another ACPI bug in 2.6:

So CONFIG_ACPI is not allowed on uniprocessor anymore, _and_ it requires
HyperThreading code? ;-) No wonder CONFIG_ACPI didn't appear for my
uniprocessor Pentium3 'make oldconfig' ;-)

(ACPI requires ACPI_HT, which requires LOCAL_APIC)

Another reason why I was saying that CONFIG_ACPI should be the toplevel
config option (even if CONFIG_ACPI never actually appears in any code,
but only in Kconfig)...
