It wasn't my intention to imply that.  The interface can be extended 
when needed.  PAT support will probably be such a case.  Changing it in 
incompatible ways isn't going to work though.

s/PAE/PAT/?  PAE is mandatory ...

Having not-yet supported stuff disabled initially is sensible IMHO.  Can 
be done for MTRR and PAT.  Is already done for MSI ;)

The lapic/ioapic stuff must be sorted though because otherwise you can't 
boot the box at all.  I think the same is true for the swiotlb bits.
