updated patch against current master, using only shell, and with a cleaner
method to convert BOOTF to a typical mac address.

it may need special handling to make sure BOOTIF is exported, such as if run
from the scripts/*-top/*.
since it's a whole block of code, maybe it could go into it's own function.
please consider applying this patch for squeeze. :)
