So I finally got ahold of a -current ofppc kernel, and ofwboot program,
wandered up to one of the big SP2 Silver nodes at work, and tried to netboot
it..  see the below:

BOOTP S = 1

I'm pretty sure it loaded a kernel.. it took significantly longer than my
attempts with the rp= fields and whatnot being hosed up.. without tcpdump on
the network, it's hard to tell..  but my best guess is that it did load the
kernel, and blew a gasket.

Note: this machine has 4 gigs of ram, would it blow up that quickly in the
process because of that?

Note2: IBM claims this is a totally CHRP compliant machine.  They could be
