boy! this *is* an early christmas present, for sure! how did you come to
this conclusion? something *must* have changed in the pci setup after
2.5.30, because the problem did not go away when i used a different NIC
driver. but i could not fiddle out the changeset to blame here, because i
failed to compile many kernels > 2.5.30.
changing one line in arch/ppc/platforms/prep_pci.c made my PReP booting a
recent 2.6-BK, patch attached.
it's booting now, "init=/bin/bash" is working, but i still can't ping to
the outside world, which is still a bit strange, but i hope i can work it out.
tausend dank (really),
Christian.
