Having done a bit of searching, it turns out a community effort is already underway with ReactX (from ReactOS), which, apparently, is entirely legal and structured to avoid lawsuits. However, progress is apparently limited by a lack of developers. While not likely at all, Valve could support the project, perhaps not openly to avoid being attacked by Microsoft. Really? I've had no problem with Linksys wireless cards (WRT-600N I believe) on openSuse 64bit and Ubuntu (I think 64 bit, may have been 32 though). I didn't need any drivers at all.
