I'm not sure if such a card exists. There are WiFi cards with free OS drivers (e.g. ath9k), but I would expect them to run some sort of firmware, too
according to wikipedia this ath9k family of WiFi controllers have both drivers and firmware as opensource. About USB controller, I didn't add xhci firmware image to my g505s coreboot and all the usb ports are working fine although at usb2 mode - so it seems to me that at least some controllers could function without a firmware, just that functionality could be degraded without one
The xHCI controller firmware and the Lenovo g505s you mention are AMD-specific stuff, which does not apply to the Intel chipset on the Thinkpad T530 (it should work out-of-the-box).
