I thought powerpc-ieee1275 platform is exactly for old world macs.

Again, I naively thought that PowerPC macs had OpenFirmware and Intel
macs have EFI. But I may be of course completely wrong here.

there are basically four families of macs: motorola, old world, new world, intel. intel of course uses eif (mostly they netboot using bsdp instead of pxe). new world and old world are both powerpc, but only new world use OpenFirmware to boot (ieee1275), old world still use the old roms. the good news is that powerbooks started using open firmware without changing cases, so you may have a new world mac, in which case it should work just fine.
