	I hadn't moved the ttys/[012] lines in inittab up before the
runlevel lines before; I just did.
	The xterms come up and I can even log in - if I do it
quickly.  Just like the serial terminal, I lose the ability to type on
the xterms partway through the boot process.  I can start up something
like top on a term; as soon as fd0 closes, I can no longer type on it and
top freezes.

	Cool...

	Your kernel is stripped - I'll rebuild and try again.

	Hmmm - when I add debug, it starts the idle and tracing thread and
doesn't get any further.
	Since you and Adam can both run it correctly, I'll play a little
more on this end and see if I can come up with more details.  I'm almost
wondering if there's something in rh / rh7 that's causing problems.
	Cheers,
	- Bill
