After reading some more of the current Libreboot documentation I don't think
that the flash chip will decide your MAC address. That seems to be the case
only for the laptops having the Intel GM45 chipset. However I'm not sure. See
here: http://libreboot.org/docs/hcl/gm45_remove_me.html#ich9gen
Anyway I'm waiting for someone to tell me if the address changed after
flashing libreboot or not. Alternatively, if someone else has a librebooted
macbook here then we could compare MAC-addresses by private message.
I'll modify the wiki after this issue has been cleared.
