Hi Joerg:
(I tried to follow-up using the gmane.org mail/news gateway... didn't seem to work.)

Please run the following commands as root (against both kernel versions) and reply-to-all with the results:
# modprobe i2c-dev # i2cdump -y 0 0x2d b 0 0x4e # i2cdump -y 0 0x48 # i2cdump -y 0 0x49
Also, can you confirm that you're using the sensors.conf from here: http://www.tyan.com/support_download_utility.aspx?model=s.s2466
Finally, can you confirm that "sensors -s" is running (without error) some time during system startup, w/ both kernel versions?
Thanks & regards,
