All appears to be working on that front.  But I'm encontering 2 problems (on master from a couple of weeks back, 7147532c):

That will be a false positive detection of an ISA NIC.

I'm slightly confused by the report: are you saying that you _are_ able 
to boot from the LOM, but only if you compile out bnxt (or use a build 
that contains only the relevant LOM driver, such as bin-x86_64-efi/tg3.efi)?
