While you could use your OSX partition as a bootstrap partition, it's really not a good idea. The bootstrap is for Linux only. As I said before, it's an HFS formatted partition that holds the yaboot binary that OpenFirmware loads. That's why it's so small. :)

If it's marked ppc64, it'll work on ppc64, the 32 bit UL uses the ppc keyword, just like the PPC32.

Yes, that should do it. The PPC FAQ has more detailed directions for configuring your kernel as well. -Joe -- gentoo-ppc-user@g.o mailing list
