Hold down Cmd-Opt-O-F while the system boots, then at the OpenFirmware prompt type 'boot hd:9,\\yaboot' (assuming that yaboot is installed on /dev/hda9; if not, adjust as appropriate). Then boot into Linux as usual and run ybin.
Or you can hold the Option key at boot, and a GUI boot selector will appear. Click the icon for the OS you want to boot, then click the right-arrow button to proceed.
