Hostap will load but WILL NOT create the wlan0 interface

I guess this was not his problem. And the scripts ( /etc/pcmcia )use the 
interface name as a parameter.

If the modules was loaded without problems, there should be at least an entry 
in /proc/net/dev, so do:
#cat /proc/net/dev

This should show all the net interfaces registered in tghe kernel, these being 
the ones you can bring up with ifconfig. One odd behaviour I noticed in my 
system was that if I configured /etc/pcmcia/config to load all three modules 
(hostap_crypt, hostap and hostap_cs ) upon card insertion, it wouldn't 
register the interface in the kernel. I have to load the first two modules 
with a insmod at /etc/rc.sysinit and just load hostap_cs upon card insertion.
