Seems reasonable to me. I'll integrate your asm diff with the other changes and give it a whirl.
This version boots into userspace on both PAE and !PAE. You want to take it from here?

ok, i'll wait for Ian to submit the final (tested) version then. A few possible complications are: PSE-less boxes, 32-bit PAGEALLOC bootups with tons of RAM, NX-less boxes and NX-able boxes :)

PSE-less should be less of an issue than making sure we switch to using large pages where appropriate, and enable the PGE and NX bits where appropriate.
