Not sure.  e300 is more or less a 603e core, which uses the same FPU
(or emulated), and trap vectors as AIM, so the total effort likely
isn't too high.  If you (or someone) wants to try their hand at a
port, it'd be a welcome addition.

As for the RB1000, trying a newer build might help.  If you still have
problems, adding "options BOOT_VERBOSE=1" to your config and
rebuilding the kernel might help shed some light on it (also posting
the full verbose boot log and kernel config).
