(Phil) OK, here is the first shot at integrating PIIX4 support in the new
lm_sensors2 project. It was *very* easy to copy-and-paste it in, so I'm
hoping that it won't include any new bugs. It builds and compiles, but
I wasn't able to test it (under 2.1.131) until we get some compatibility
problems solved. There is probably a little cleaning up to do yet, but
everything looks like it is happy. Test it under 2.0.x and let me know
what happens.
