According to the Wireless LAN Howto at:
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/
the wvlan_cs module is no longer being maintained and has been replaced by the orinoco_cs module. So, the module being loaded is actually the correct module.
It sounds like you should see if there are updated application packages available.
Failing that, you should be able to manually unload the orinoco_cs module and load the wvlan_cs module, which will allow you applications to work.
Try using rmmod orinoco_cs to remove the orinoco module and try using modprobe wvlan_cs to load the wvlan module. I'm not certain this will work with the pcmcia modules (or even that the names or correct), but it's the first thing I'd try.
