The main issue is that changing that is a very very invasive change in an extremely fragile and rather nasty area of code shared by 32 and 64- bit for which we don't even have easy access to all the machines to test with anymore :) It's probably not impossible, but it would delay the new cpu feature stuff that Nick is making by a lot, probably monthes, making it nearly impossible to get back into distros etc... So while it might be something to consider, I would definitely keep that as a separate unit of work to do later.
