mac filtering with policy maps

I've been looking for a way to filter macs on the lan side of a 871 router.  The following works to deny a list of mac's from passing traffic.

class-map match-any macfilter

match source-address mac hhhh.hhhh.hhhh

policy-map macfilter

class macfilter

    drop

I've applied the service-policy to a vlan interface and it seems to block traffic from the designated mac address.

Is there a way to turn this around and use a class map to list mac addresses and apply that list to policy that will pass traffic on that list and drop anything that is not sourced from the mac's listed?

Thanks
