OK, so looks like a limitation of grub then, maybe related to ffs2. I use
only ffs1, and never had problems.

This would still be a different boot loader than one the we have now,
because Xen expects completely different things. And you still want
to be able to boot a native i386 kernel :)

As domU, more or less. There is PTE corruption in some situations, but
I've also been able to complete build.sh release sets.
As dom0, not yet.

It will, but you may not have the last linux kernels available.
I have some linux domU running.
