Hmm, getting FC6 to work would be nice. Will see what I can do (have
to convince my supervisor to do the change ;-).

For my purposes, I think it'd be easier to just set up a tftp server
with the kernel on it, and not using modules; this is what I've done
for NetBSD kernel development for a while and is useful enough. I've
yet to get tftp to work from kboot though.

Will try that tomorrow.

OK, you're right.
