Thanks.  I do think it would help if you could go through the details
of a couple of tables and a couple of DSDT entries and walk through
where each field will come from.  And also describe how seabios will
build the resulting AML.  From my previous email:

I do understand your desire to pass this stuff as parameters, but I
really don't see it as feasible.  I'm hoping that if you can write up
some examples with specifics you'll either enlighten me or you'll see
the difficulties I'm trying to describe.
