  That's a bit strange: looks like yaboot was trying to load the FreeBSD 
kernel.

  You'll want to boot the loader from the cd. It should load the kernel,
and then give you a timeout period where you can hit the space bar to 
break into the loader instead of booting the kernel i.e.

0 > boot cd:,\boot\loader cd:0

  No, FreeBSD will install on *any* partition type, but you need to keep 
at least one HFS+ partition to install the loader onto so that 
OpenFirmware can read it in and boot it.
