I had already removed .zrom before I saw your mail, sorry:

I've modified and applied your "allmroms" patch:

There is a substantial caveat that I should mention regarding "allmroms".  
.mrom will not work for all ROMs; it requires a NIC that has both an expansion 
ROM BAR, and at least one memory BAR that is at least as large as the 
expansion ROM BAR.

Unfortunately, it's not possible to determine from the PCI vendor:device ID 
whether or not these requirements are met, because some vendors use the same 
vendor:device ID for PCI cards (which do have an expansion ROM BAR) and LoM 
parts (which don't).

For the time being, at least, the decision to use .mrom rather than .rom is a 
non-trivial manual decision.
