The 824x series are essentially G3 family CPUs.  The amount of effort 
required to bring up this CPU would be amount the same amount of effort
needed to bring up a new ARM9 CPU.  The only thing that complicates it
is that the current ppc support is really tailored for the Mac platform,
so it assumes access to OpenFirmware during bootup.  That said, MPC824x
and IBM 4xx series support would be awesome for getting into appliances
that specialize in DSP.
