I use the following syntax, to bring up a MiniPCI wireless network
interface with no address, so it can be added to a bridge. Different
purpose but same idea, I think.
auto wlan0
iface wlan0 inet static
address 0.0.0.0
netmask 255.255.255.254
Nothing actually gets added to the routing table, AFAICT, but it's
necessary to specify a netmask to stop ifupdown from complaining.
