Okay, what about this one: You merge xen hooks in mainline, but keep maintaining arch/xen out-of-tree? You have to maintain it yourself, anyway, and having hooks merged should make it easy. When xen is merged into i386 (you said that is your long-term goal anyway), you can merge that into mainline...
