Well, that helped out a little bit - at least it gets the right address
and attaches the ite0! But I guess there's still something else that's
very fundamentally wrong, since as soon as I start up X (xdm, actually) it
clears the display to all white (_not_ the pseudo-gray background) and
then gets an MMU fault.
Oh, and on its way to MMU fault, I got a couple of those "freelist data
modified" messages that someone else mentioned the other day...
Oh, well, I guess I can live without X for a while longer.

Yep. If X had been running, I'd have just cut-and-pasted it instead of
having to retype it! :)
