i have an emachines m5310 that im trying to get slackware to run on so i can ditch windows, heres what ive done so far...
1) installed slack with bare minimum, no games; kde; gnome; no extra apps; no emacs; no docs; etc.
2) upgraded to the 2.6.8.1 kernel, i made a very bare kernel with ONLY what is needed to boot the laptop.
3) the first thing i want to get to work in the kernel is power management, i installed apci, with cpu-scalling and the powernow-k7 module. when i boot up i can see that it does in fact detect the different power modes for my laptop.
my question is, how do i actually use powernow. ive managed to change the cpu speed but i dont think its changing the voltage. theres not much documentation that i could find that helped me. from what i understand cpufreq is depreciated and is no longer use. so please can someone help me.
one of the only things that i found semi usefull is this program i found,
http://gandalf.ics.uci.edu/~haldar/lamp/ but im a little reluctant to use it if i can control the speed through the kernel instead of a 3rd party app.
