For example, DP_WLAN-WiFi_23101.7zBroadcomFORCED5x86BCM43_6.30.223.228bcmwl5.inf is for NTamd64, and has to be modified to read NTx86 to install, at least through device manager on XP/2003 x86. Multiple other drivers in the folder appear to be NTamd64 as well. All of the ones I checked have x86 .sys files, so it should be as easy as an inf swap.
