It does not however preclude fixing the dom0 interface.

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.

MTRR, PAE etc can all be turned off for the purpose an initial merge.

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.
