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. > Given my list of cards, are there any other general pointers as to > which bus which cards should go? 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... > The order I have now took a long > time to create - I'm not sure if it's the unique workable one, but > several other orders cause OpenTransport crashes when I am running > the ixTV (!). 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.
