i've looked at it.
what do you mean by PAE support? what would plan 9 need to
do to play nicely with xen3?
pae is already recognized by plan 9, but the default memory types are not
fiddled and you can't map a region with a specific pae type.
these changes are not too hard, but i haven't gotten to a place yet
where i need to implement anything but it may be that setting up
wc pci space will be necessiary for good performance with some
pcie drivers.
