For an e500mc guest you most likely want to run with -M ppce500 and 
enable QEMU machine support in your guest kernel.

I don't think there is an Ubuntu kernel for e500 chips. Please try to 
compile your own kernel and see whether you can run that one through 
-kernel. The e500 machine models don't supply any firmware, so passing 
in a -kernel blob is mandatory to get them working.

To get you started quickly, please give this uImage a try as -kernel 
binary: http://csgraf.de/tmp/ppc/uImage.e500mc

  $ qemu-system-ppc -M ppce500 -cpu e500mc -m 1G -nographic -kernel 
uImage.e500mc
