No devices would work until I manually loaded yenta_socket. Before the change, the PCMCIA bridge was
discovered earlier, and yenta_socket was automatically loaded. Now I need to add it to the list of
modules to be loaded at bootup. With that change, everyting is OK.

The diff between yenta as a module and yenta built is follows.

Thanks,
Larry
