IIRC the bridging module is only for ethernet, so you will either have
to find a way to make your ISDN/DSL card appear as an ethernet device
(if it isn't already - I don't have dsl), or switch over to routing.  I
believe there was a patch floating out there that converted ppp/dialup
connections to ethernet so I believe it can be done, but I'm not sure if
the patch still works or can be adapted to your needs.  Check out
lartc.org for the patch - maybe? 

Sharing the dvb card ... can it be done?
