The kernel-pcmcia package doesn't contain the /etc/pcmcia/network.opts file.
The PCMCIA package shipped with Red Hat Linux does not require /etc/pcmcia/network.opts to be present to work properly. From my understanding this fail is not installed by default in 5.2 or previous versions. Please check this URL for more information. Options are normally added to /etc/sysconfig/pcmcia. http://www.linuxhq.com/HOWTO/PCMCIA-HOWTO-2.html#distributions
