I'm not on a Linux box at the moment but isn't there an eth0 entry in /sys (or maybe /proc) which can give you mac address in easier to parse way (I think you could just use cat). I don't know if they are still in vogue but /sys and /proc interfaces were originally intended to return clean output which is easy to parse in programs and scripts. I guess usage never really caught on.
