Force's PowerBoot doesn't properly clean up caches before handing
control over to an external program.  You are probably having
cache problems that we have run into on some COTS Force boards.
I had to disable, flush, reenable L1 icache on the 680/G4, for
example.  linuxppc_2_4_devel's simple bootloader has a specific
CONFIG_PCORE option for this, in fact.
