For some reason, booting into Mac OS X changes the open firmware
default boot settings.
You have two options:
1. You can hold down four keys while rebooting to make the
machine boot into open firmware. Those four keys are:
option cmd o f
Once you have the open firmware prompt, you can issue
the command:
boot hd:XX,yaboot
Where the XX is replaced with the partition number of
the boot sector (it's 10 in my case).
2. Or, you can follow the instructions Dan gave me to
reprogram open firmware:
setenv boot-device hd:10,ofboot.b
reset-all
Open Firmware is a pretty neat system. See TIL Article #60285 for
a basic introduction.
