For reason I don't yet know we got Cisco Broadcom 10g NICs in our servers, and while they do have warranty coverage they are not under a Support contract, and so no firmware upgrades available.

I was able to use the Broadcom diag CD to push non-Cisco firmware to most of the card. I say most, as it contains three or four firmwares, and one firmware would not upgrade. However we were able to get what we needed and move on.

I would not recommend this process as bricking is a possibility, and there is possibly unknown issue with mixed firmwares. I will be spending time plugging the support hole or replacing these cards with suitable OEM'd ones.

Now off to play with iBFT.
Thanks Bitt and Trevor for the assistance.
