Ok, I've been unable to work out what is wrong with the NII driver on these systems, but I *have* been able to work out why the PCI device probing wasn't working correctly and causing iPXE to fall back to NII in the first place.  At least the 1G Broadcom (BCM5720) driver then works as expected and is able to pull images via http without issue.

I'll cleanup and submit a patch.  Does ipxe have any sort of additional contributor agreement?  (As this was done on work time, I have to ask and go through the motions to get approval from my employer, etc).
