 so it is probably something related to how the second stage should identif=
y the boot device.

Maybe the raw disk access (without partition translation) does not
work. There was something on OpenBIOS list recently for PPC:

IIRC the CD-ROM drives used by Sun were slightly different from
standard SCSI models, something like the block size could be 512 bytes
instead of 2048 or vice versa.
