I don't know the model of the board off the top of my head.

I do know that it uses the Texas Instruments XIO2000A/XIO2200 PCI  
Express-to-PCI Bridge (rev 03), with the TSB82AA2 OHCI Link behind the  

The same board definitely works as expected in a Mac Pro.

In doing some Google searches about this, I have seen the TI part  
listed in the PCI configuration of folks running linux (though  
probably on Intel) and apparently having no problems with the busses  
behind the bridge being enumerated.

I am guessing that the problem is related the the PCIe root complex on  
the 8377, but I am just guessing.

Is PCIe known to work on the MPC837x?
