I saw the patch (just after sending my previous mail in fact), but as Alan pointed out it doesn't quite fit in to the style requested by Linus. I'll be giving it a shot after Wednesday (last exam), unless you want to try fixing your patch - potentially my first public kernel patch...

WinChips should be straightforward to detect - they can't report anything they can't actually do (see Alan's message for more info). IDT have got documentation on their web site at www.winchip.com; see in particular http://www.winchip.com/2_detailedspecs.html and the actual datasheet, http://www.winchip.com/pdf/C6DS.pdf.
