AFAIK /dev/pmu is the device interface that provides access to the power 
management. Although it is said to be for powerbooks, i used it on my 
imac and that allowed me to put it to sleep and such. You need to 
install pmud and enable pmu in your kernel (if you built your own). Then 
you should be able to run pbbuttonsd.
