Actually I think you just answered your own question ;-)

Anyway, I don't think an initrd solution is the best. Yeah, it's fine
for a work around, but then I need to go and screw with the initrd if it
doesn't have support for the board. If the network card already has a
MAC address, why should the kernel give it another *random* one?

This isn't a complex patch set, where the complexity should be put into
userspace. And it makes it very convenient for people that just want the
board to boot so they can test it. I'm not developing any SoC or BSP,
I'm just using it to make sure my kernel changes can also be implemented
for ARM.
