You must RTFM the PPC440GX UM in PLB-PCIX Bridge Controller chapter.
In the PCI Arbiter section, it tells you how to set CPC0_STRP1[PAE]
to enable/disable the internal PCI arbiter. They didn't even try to
hide it...

Please don't post the same message to linuxppc-dev and linuxppc-embedded.
Pick one or the other based on the list description.

See the UserManual for all the details... but the arbiter enable/disable
is a strapping option. If you do not have a serial boot prom, then the
arbiter is off by default. You can override this in your bootloader by
poking a register. Seach the manual for "PAE" (Pci Arbiter Enable).
The register is SDR0_XCR, bit #0 (page 347).
