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...

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).
