Not yet, but it's easy to make it so, especially if somebody tells me
the thing I need to look for in /proc/cpuinfo. Is it just "pae"?

The trickier issue is that in order for this to be a useful choice, we
now need to cram two kernels onto our CDs, otherwise either (a) non-PAE
users are just screwed or (b) PAE users don't get any advantage unless
they install via netboot or a DVD. Has this been discussed? I don't see
a record of it in the specification.

is what I was referring to obliquely at UDS. Maybe somebody should poke
Kyle and find out if he has the patch set to hand.
