Passive interface commands though used under several routing protocols, have to
be listed explicitly in the desired routing protocol's configuration section,
so you should be able to use the passive interface command under OSPF, but stil
l have EIGRP function as usual on the same interface ..

Passive interface is for all routing protocols.
Eigrp and ospf adjacencies are not formed if it is used.
