(First, thanks to the many people who helped out with my previous obvious
question.  I should have had more faith, it worked the way it really ought
to have (well, aside from the built-in boot program being cretinous, but
that was easy to replace, as many suggested).)

Now, I have a Diamond Stealth 64 2001 PCI graphics controller, on which I
would like to run X windows.  The manual does not, of course, explain what
chipset is actually present, and what's worse, SuperProbe cannot find it.
I suspect that this may be because of one of those "unknown PCI controller"
boot messages.  Is anyone else running one of these successfully, and if so
what do I need to do to make it work?  Or, am I definitively out of luck
until the PCI support improves?
Thanks,
John Woods
