Not that I disagre with utilising the PAT, but I don't see anything in this code to deal with the widespread PAT indexing erratum in Intel's processors. I don't have the errata sheets here, but it definitely affected the PIIIs and I think also some P4s. (Large pages ignoring PAT index bit 2, or something like that.)
