Building the table by hand is trivial in the case where the processors
are just _listed_, and can be easily justified. This first patch just
add the _STA method, but other follows, which turns the processor block
into a quite complicated thing. Not to mention the operational region,
the notifications that have to refer to the processor objects, etc.
So I can't see any valid justification for using the code in
rombios32.c, instead of a high level language such as the one provided
by acpi.
