Hi James,
I had a similar problem to this with a usb card. I'd modified
the /etc/wlan/shared script and saved a backup to shared.old.

Unfortunately, shared loads & runs all /etc/wlan/shared.* so

shared => shared.old => shared.old => shared.old ....

leading to 100% cpu, no free memory & hotplug seemed to keep creating
new wlan.agents.

Therefore check /etc/wlan for extra copies of the shared.* script. 
I think there should only be one, shared.prism2, but I'm not sure what
difference pcmcia makes.

HTH
Cheers
Richard
