Don't worry, only slightly ;-)
Yes, I boot my workstation in the office with yaboot, and indeed the path is
openfirmware->yaboot->ELF-kernel(in an ext2fs).
As you can see yaboot mediates between the openfirmware, ignorant of ext2fs,
and the linux kernel. I haven't checked whether the firmware can launch ELF.
By now ELF seems to be the format of choice already for anything surrounding
OpenBIOS, so no problem with that. All that's left is (readonly!) ext2fs
code, as in FILO or GrUB (or yaboot :-); and as one can see in these
projects, it's not such a big deal. We'll probably see a forth version of an
ext2fs well before someone seriously starts using yaboot.
