Pity - I can't, because the K8 sensors are only recognized from 2.10 on.
But I have another indication that may be helpful. I switched back to
kernel 2.6.18 and the sensor-plugin started working again. 'sensors'
works with both 2.6.18 and 2.6.19. Sensor plugin doesn't with 2.6.19.

I have no data at all from the harddisks. Only the header 'Hard disks'
appears on the sensor-plugin setup combobox. When running kernel 2.6.18,
also the w83627 sensors appear. (with valid data)

I've checked now, and there is no other xfce4-sensors-plugin.desktop on
the entire disk. And its date coincides with the compilation date.

PS: The distro is mainly Slackware 11.0, though some parts have been
updated by me (such as the kernel). libsensors.so.3.1.1, and
hddtemp is not installed.
