If it's the Proliant 3000, it does indeed have two host-pci bridges.
Here's the dmesg output for a box running 3.2-STABLE.
(Those of you with sharp eyes might wonder about the memory lines. The
box has 576 MB memory. We had some stability problems, and I suspected
part of the upper memory was being used by the BIOS etc - so I made a
kernel with MAXMEM of 572 MBytes. Later it turned out that the stability
problems were probably due to insufficient mbuf clusters. After we upped
this to 4096, the box has been extremely stable.)
