Hi Dietmar,

   Yes, I think we would want a mini-os port in the source.  Skimming
through the patch, my first impression is that this seems more like a PV
port of FreeBSD than a truly "minimal" OS.  If we're designing an OS to
run only in PV mode on Xen/ia64, can we remove some of the ia64 bare
metal components?  Perhaps ripping out some PAL/SAL/EFI/ACPI specific
layers?  And if we do need those components in a mini-os, would it make
more sense to leverage them from Linux than FreeBSD?  Maybe some
discussion of your design decisions would help me understand better.
Thanks,

        Alex
