Hmm -- ok. There's a fair chance I'm going to stick with the fdisk
partition anyway, to let me boot FreeBSD in native mode, but I'll see.
(FreeBSD has better IPMI support; if I need to get at it at that level,
I'd need FreeBSD. Hmm -- I wonder. I can assign the PCI ports to the
FreeBSD domU; maybe that would work. Hmm... (The right solution is
for me to port the FreeBSD driver to NetBSD, but I'm not sure I'll have
time to do that before putting the machine into production.))
