That's a great find. (at line 5250). Also note that at line 3158, it checks for PIIX4, and if not there, the comment says definitely not a Thinkpad. I'll put the 3 ID's from line 5250 into piix4 as a 'blacklist'. Can somebody do the same in sensors-detect? (check for those 3 ID's, if one is present, exit with a message). We may need an lspci -n output from every thinkpad on the planet. Or maybe just reject any board that has any IBM device at all? phil at netroedge.com wrote: > > 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.
