Hello, i found this bug which was the reason, that sensors couldnt find any sensors, altough it should have with the lm78 driver.
khali wrote a patch and i tested it and it works now. Here are some further information:

Subject: hwmon: (lm78) Fix I/O resource conflict with PNP

Only request I/O ports 0x295-0x296 instead of the full I/O address
range. This solves a conflict with PNP resources on a few motherboards.

Also request the I/O ports in two parts (4 low ports, 4 high ports)
during device detection, otherwise the PNP resource make the request
(and thus the detection) fail.

This is the exact same fix that was applied to driver w83781d in
March 2008 to address the same problem:
