Hi, I'm currently in the process of doing something very similar to this.
Yesterday, I removed the Broadcom wireless card that came with my Mini 9 and installed a Broamcom Crystal HD video decoder. In order to still have wireless capability I also soldered on a Mini PCI express header in the WWAN spot in order to install a USB interface Mini PCI express network card.
The only one I could find (and therefore went with) is this one: GN-WI05GS-RH (1.0) - GIGABYTE - Product - Communication - Products
This card looks very similar to the one you happened to find. They appear to both utilize the USB interface of the Mini PCI express interface and they both use the Ralink RT2571WF chip and drivers.
When I installed my card in the WWAN bay last night, the drivers were actually found by Windows by Windows Update and they did install correctly! The only caveat is I cannot get the radio to turn on! The Dell BT/wireless utility doesn't work nor anything else I've tried so far (linux, various other drivers from MS, Gigabyte, and Ralink).
After reading this thread and looking at the specs for the card you found I think I have an idea of what is causing this. Your wireless card appears to have pin 20 designated as a radio on/off signal. When the voltage is pulled high the radio gets enabled, when left low it is disabled. I think this is the problem I am witnessing and I might try wiring that pin high on my setup to see if that fixes my issue. I am also curious how the WWAN cards' radios are controlled, whether it is in a similar fasion (possibly with the same pin). If so, I might try to install Dell's software for the WWAN cards and see if I can enable my WLAN radio that way.
Anyway, I hope this goes smoothly for you but I anticipate you will hit this issue too. I'll definetly reply here if I can get my wireless radio to turn on.

Well glad I was able to help, even if it was unintentional.
Also, the QCom WLAN card showed up, I popped it in, and everything seems to be working fine. Would you happen to have a voltmeter handy? If so, maybe try measuring the voltage on pin 20 to see if it's high or low. I was assuming before that low means the radio is disabled, and high is enabled, but I think it's the other way around. If you're getting high on pin 20, try running the Dell WWAN software and set the radio to always on, maybe that will set the pin low.
