Are you sure the machine in question actually is a PowerPC system
as opposed to a POWER architecture RS/6000. LinuxPPC will not run on
POWER architecture as LinuxPPC uses PowerPC instructions and memory
management is different.
The pre-PREP / pre-CHRP RS/6000 loaders are extremely simplistic,
but I do not know the details. If it understands XCOFF, then it might
look at the entry point for the "application" in the header to know the
starting address.
