whacked out 2.2.18pre17?

Mine is a 7600 (first generation PCI as well), and I have a G3 upgrade
as well... but 2.2 kernels have always booted for me. I have no luck
with 2.4 kernels... no way to reliably boot those.

That's probably because imsttfb looks for the device in the OpenFirmware
device tree, not in PCI device tree. And, since OpenFirmware uses tat
display, it is available anyway to offb. Keep in mind that it's absence
on the lspci listing doesn't mean it's unavailable. It's just invisible
to drivers searching the PCI device chain.

Well, only that you should know all your 'internal' devices are on PCI
bus 0 (that is, top slots, AFAIR). Internal and external SCSI count
here, as well as built-in ethernet and the serial ports. So, if you use
your internal SCSI as well, you might want to exchange the Matrox with
either the SCSI or the ethernet card. But it depends on your usage as
well...

In that case, there might not be too much gain in swapping your cards
around... If you do graphics-intensive thngs on dual monitors, maybe
swap the matrox as said above; but other than that, it's probably ok.
