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.
