Right, there's a PCIX bridge that is failing to attach, leaving the bus and devices behind it invisible.  I believe that the failure is because the bridge is seen in the PCI register scan, but not in the ACPI AML.  Because it's not in the AML, the acpi_pcib driver vetos the attach.  I believe that if the machine was booted with ACPI disabled, all of the bridges+buses+devices would be seen regardless of what slots they are in.
