Basically, I taught yaboot to recognize 0xfd (Linux Software Raid)
partitions.  If yaboot finds one of those that it knows how to read,
and sees boot information, it'll boot from it.

disks in a mirror.

And you should configure your boot order in your bios/firmware to
failover to each disk in the raid.

If you have more detailed questions, please feel free to ask...
