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).
