Not sure if this helps or not, but we've got about 20 of these machines, 
as well as the DL580 version in production. I've seen this very same 
issue on the ML series machines also. If I remember correctly, there 
were two different PCI bridges used in the same production models, one 
was from IBM and the other was a ServerWorks (Broadcom) chipset. One 
didn't show up at all (not even when probed) and the other one was 
displayed. Can't remember which was which, but I know it had to do with 
hot-swap PCI subsystem, and I suspect this is what you're experiencing. 
We had a similar experience with MyriCom 10GE cards in an ML570 with a 
hot-swap PCI option. The card wouldn't show up in slot closest to the 
Mem card (can't remember if the DL380's have a riser card for ram or if 
this is onboard), but it worked in the next slot over.
