Interestingly enough, I had a chance to try the ndis driver (using 
Broadcom's Windows XP driver) and it fails almost identically:

ndis0: <Broadcom NetXtreme Gigabit Ethernet> mem 0xd0000000-0xd000ffff irq 
16 at device 0.0 on pci2
ndis0: NDIS API version: 5.1
ndis0: NDIS ERROR: c005000e (%)
ndis0: NDIS ERROR: c0050014 (%)
ndis0: init handler failed
device_attach: ndis0 attach returned 6

That and Martin's success with the same chip lead me to believe that the 
problem may be with PCI express on this mainboard and not the BCM5751 
specifically.  As far as I can tell, the NIC is the only PCI-e device in 
this system, and unfortunately I don't have any PCI-e expansion cards to 
test with.

I'm in the process of updating the box to today's -CURRENT.  I'll post what 
I learn from that, if anything.

I looked through the sources for both FreeBSD's driver and Broadcom's Linux 
driver, but I was unable to find the link between the printed ASIC rev. 
number and the code.  I'm no expert programmer (expecially wrt device 
drivers), so I'm obviously just missing something.  Pointers?
