Incidently, in the kernel drivers/sound/cs46xx.c, it checks for a 600E and 600X series Thinkpads by checking for the existance of some specific PCI devices. Parhaps it's just as easy as looking for one of a series of specific PCI devices to detect for a Thinkpad? On linux-thinkpad.org they list the vulnerable Thinkpads as: ThinkPad 770X ThinkPad 600E ThinkPad 770Z ThinkPad 600X ThinkPad 240 ThinkPad X20 ThinkPad 570E It would be nice if we could detect for any Thinkpad, but we might be OK if we just were able to detect the above? Here's a list of know PCI ID's, which might be useful: http://pciids.sourceforge.net/pci.db The names here don't quite match with the scheme above, though...
