This is entirely possible, the max1617 has very bad detection (no
device nor manufacturer ID) so false positives are frequent. We should
probably drop detection altogether.

Note that the lm75 driver only detects the original LM75 devices. Other
supported devices such as the TMP75 need to be instantiated explicitly.

Universal detection was only added to the coretemp driver in kernel
2.6.35, while Jerry runs kernel 2.6.32.
Jerry, please try the stand-alone coretemp driver at:
This is basically the version from the latest kernel, with some
compatibility bits added so that it builds and runs on older kernels
Installation instructions can be downloaded from:
This is a document I just wrote, let me know if it contains errors or
can be improved in any way.
