I looked into this several years ago, it's actually fairly gnarly since
depending on PAE we set up the swapper page tables differently, and
other ugly differences.

I should resurrect the patch set, though I think rationalizing it with the
Xen merge might be more pain than it's worth... last time I looked at it
there was a ridiculous amount of rejects.

It was pretty close to booting (though I had to hack the bootloader to
get a PAE enable bit so people without the bit could turn it off.)
