Kind of depends on what mode the firewall is in. If the firewall is running in transparent mode then pass the OSPF traffic through. If it is running in routed mode it needs to participate in OSPF routing.
That is the problem. OSPF expects to form ajacencies with neighbours on the same network but you have another hop between your 2 ospf routers because the firewall is in routed mode. That is why you can run OSPF on the FWSM itself in routed mode to get around this problem.
The only way the 2 ospf routers on either side of your FWSM will see each as neighbours is if the FWSM is in transparent mode ie. the same subnet on either side of the FWSM.
Wouldn't it be possible to configure a GRE tunnel between the 2 routers through the FWSM/PIX/ASA (allowing the correct ports to go through of course) for OSPF traffic? Seems like that would enable the routers to see each other as neighbors.
