Sorry guys. I cannot help much more on PCMCIA since I only use the mini-PCI one.
Theoretically, the PCMCIA update should work with the patch but probably firmware updater is also checking some other stuff beyond PnP ID that was fixed to get it working with miniPCI.
One last shot... Can you tell me the following values from your registry on your system (when using Dell Drivers)
Look at each subkey under this. Please tell me the "ComponentId" and "MatchingDeviceID" values when "DriverDesc" or "VendorDescription" values are "TrueMobile 1150 PC Card".
For example it should look something like (from my mini-PCI)
Well Dr TCP I only show one dell adapter, here is a copy of that registry branch and the requested screen shot -- The difference between foresight and hindsight is only a matter of when you bother to think things through.
