Weird PCI/PCIe enumeration on PowerEdge 860s

Hi,

I'm configring a new PowerEdge 860 server. It has two onboard Broadcom 
ethernet ports and I've put an Intel Pro/1000 PT Quad Port GigE card 
into one of the PCIe slots. The OS is Ubuntu 6.06.1.

Here's a snippet from dmesg:

[42949389.280000] e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network 
Connection
[42949389.500000] e1000: eth1: e1000_probe: Intel(R) PRO/1000 Network 
Connection
[42949389.740000] e1000: eth2: e1000_probe: Intel(R) PRO/1000 Network 
Connection
[42949389.960000] e1000: eth3: e1000_probe: Intel(R) PRO/1000 Network 
Connection

(PCI Express) 10/100/1000BaseT Ethernet 00:15:c5:fc:5c:28

[42949389.970000] eth5: dma_rwctrl[76180000]
[42949394.160000] tg3: eth1: Link is up at 1000 Mbps, full duplex.
[42949394.160000] tg3: eth1: Flow control is on for TX and on for RX.
[42949412.780000] eth1: no IPv6 routers present


So, everything was going OK until towards the end, when tg3 decided it 
wanted to be eth1, when e1000 already was. Linux problem, BIOS problem? 
Any insight would be useful.
