Sensors and pwmconfig

[Barry Samuels <barry@beenthere.mail1.co.uk>]

Debian Squeeze/Testing
Kernel 2.6.26

I've installed the lm-sensors package and Gkrellm will display both 
temperature and fan speed. If I run 'sensors', however, I get:

Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and libsensors
was compiled with sysfs support!
For older kernels, make sure you have done 'modprobe i2c-proc'!

I've checked that sysfs is mounted.

pwmconfig when run produces:

/usr/local/sbin/pwmconfig: No sensors found! (modprobe sensor modules?)

Are these problems related and can anyone advise me what to do to get them 
to work?
