Yes, it should.  Just be clear that *that* is a semantic change over 
what the code currently does; it would appear that that is what the code 
is *trying* to do.

I believe on x86 it will still get clamped by the MTRRs, at least 
initially (I don't think we have flipped the default MTRR type to WB 
yet) but that would immediately change the behaviour on non-x86 
architectures.
