When building the Pegasos2 machine stand-alone we get:

 $ qemu-system-ppc -M pegasos2 -bios pegasos2.rom
 ERROR:qom/object.c:714:object_new_with_type: assertion failed: (type != NULL)
 Bail out! ERROR:qom/object.c:714:object_new_with_type: assertion failed: (type 
!= NULL)

Looking at the backtrace:

 Thread 1 "qemu-system-ppc" received signal SIGABRT, Aborted.

The "isa-pit" type (TYPE_I8254) is missing. Add it.
