This should not be too hard to do. 

You need to make sure
 * that the option rom space of the network card is mapped to a free
   space of physical memory.
 * to use that memory space instead of the "below 4G" area for flash

That's about it. The first step will definitely be harder. Early
versions of Linux mapped all PCI roms into physical address space, so
back then this was an easy method. 

Patches welcome ;-)
