Regarding the sub-thread on x86 emulation, that is totally out of scope
for this. The 'AtomBIOS' of the ATI cards, consists of multiple parts (I
may have minor errors here, ask airlied if you need more
clarification):
a) Initialization code (I think arch-specific)
b) AtomBIOS script interpreter (I think arch-specific)
c) AtomBIOS scripts (card-specific, but not arch-specific)
d) Data tables (card-specific, but not arch-specific)

The AtomBIOS parts of the various drivers need data from c+d primarily,
and provide their own script interpreter, or not using the scripts, just
the data tables.

Are you sure the X1900 Mac Edition ROM contains any ATOM data structures
though? I rather doubt it.
