I wonder if it may have something to do with the different ppc firmware
revisions. May it be that the newer kernels somehow dislike newer versions
of the flashrom on cyberstorm and blizzard cards, and therefore crash on those
machines, but work on older ones (like mine or yours) or vice versa?

IIRC there have lately (year 2001) been some new updates floating around to
support pci bridging boards. Maybe we should have asked about the firmware
revision in the poll.
