We ended up in this same situation, and went down the Intel PCI express 
NIC path (Intel Pro/1000PT). Be advised that, at this stage, the driver 
in both 6.0 and 6.1 -RELEASE does not support this card, but support is 
present in 7-CURRENT.

That being said, with the official Intel driver (v6.0.5, not sure if 
it's released yet), I was able to replace the standard em driver in 6.0, 
build a new kernel, and bring the server up and survive some 
pre-deployment load testing without any hiccups.

Be aware that while the riser card has two PCI Express slots, one is 
half-height, and the Intel NICs (at least the one we received) are a 
full card.

The onboard Broadcom NICs weren't worth the PCBs they were printed on in 
terms of stability -- we were seeing the same hard lockups as Ted and 
didn't have the luxury of time to spend fiddling with it!! From what I 
gather from Ted's previous investigations, there's various work-arounds 
in the Linux driver that work around some shortcomings in the hardware
