This machine uses the Valkyrie display device, and in 2.1.24 this is handled by directly accessing its memory, whereas in 2.2.18 it is accessed through OpenFirmware. OpenFirmware is known to choke on this machine when using the display (as in CLAIM failed). My suspicions were aroused when, after disabling CONFIG_FB, the machine booted cold without any problems whatsoever. Is it at all possible to use Valkyrie without going through OpenFirmware at all? It is not selectable if I disable CONFIG_FB_OF. Would it be possible to port the older non-OF driver to the newer kernel? What are the disadvantages of using the older memory-based driver to the newer OF-based driver? Thanks. -- .-.
