acpitable.c was written to support machines with a bad MPS table but a valid
$PIR. The 20011218 ACPI patch more closely integrates that code with the
rest, but the ability to get at the MADT (the ACPI MPS replacement table)
and other tables without the interpreter is still supported. The code is
under drivers/acpi, though.

I don't see that option going away any time soon.

However, without a valid $PIR (which is what is becoming more common and is
the Sony's problem) you need the interpreter, like Kai mentioned. We are
working to incorporate Kai's code into the next acpi patch, which will
evaluate and use _PRT properly. In fact, that's just what I was working on
this afternoon, so Real Soon Now. ;-)
