Probably not.  I've only done this on the MPC8360eMDS.

Looking at the "ToDo" table it says that
needs modifications to ft_board_setup() and
needs modifications to ft_cpu_setup() (you should be able to copy what I 
did for ./board/mpc8360emds/mpc8360emds.c and ./cpu/mpc83xx/cpu.c with 
some minimal mods).

If that isn't the solution, I don't know where the problem lies.
