There's one in the cobbler source code (which was pulled from xen).
Something like this perhaps:

$ cat /tmp/genmac.py
#!/usr/bin/python

import random

def generate_random_mac():
    """
    Generate a random MAC address.
    from xend/server/netif.py
    Generate a random MAC address.
    Uses OUI 00-16-3E, allocated to
    Xensource, Inc.  Last 3 fields are random.
    return: MAC address string
    """
    mac = [ 0x00, 0x16, 0x3e,
        random.randint(0x00, 0x7f),
        random.randint(0x00, 0xff),
        random.randint(0x00, 0xff) ]
    mac = ':'.join(map(lambda x: "%02x" % x, mac))

    return mac

print generate_random_mac()
