I have a 5751 based PCI-e card working in an Intel D945GNT board here:

pcib8: <ACPI PCI-PCI bridge> at device 28.5 on pci0
pci8: <ACPI PCI bus> on pcib8
bge0: <Broadcom BCM5751 Gigabit Ethernet, ASIC rev. 0x4001> mem 
0x90200000-0x9020ffff irq 17 at device 0.0 on pci8
miibus0: <MII bus> on bge0
brgphy0: <BCM5750 10/100/1000baseTX PHY> on miibus0
brgphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX, 
1000baseTX-FDX, auto
bge0: Ethernet address: 00:10:18:11:bc:f4

I notice that yours have a higher ASIC rev.

There is an open source Linux driver available at www.broadcom.com check 
if they are doing something special with different ASIC versions there.
