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.

If anyone is interested, I think I can bring up a DL380 g4 so someone can
fix it, if there is interest. Probably got even a SmartArray or other PCI-X
card that can be plugged in.
