Yes, value changes with no effect when hotkeys are pressed...I am not 
sure why there is no effect.

The fan is horribly noisy on this model. However, it will quiet down a 
bit on its own when temperature goes down...enabling C states and 
running "powerd -a adaptive -b adaptive" should help a lot...I don't 
recommend manual fan control as at least my i7 already runs way too hot 
in linux and win7 (for the 10 minutes I had it :) ). Run Lenovo bios 
updates as well, many complaints about post tsunami fans from Lenovo 
China instead of Lenovo Japan...

Only the fan speed value shows as 0xFFFF or something, however it can 
still be set 1-7 or back to automatic as usual

I'm not sure...that might be accomplished with dpms.ko, haven't tried....

On Konstantin's page he mentions this...it's a known issue
