Someone mentioned powernowd. It did not work on my Athlon XP system:
powernowd: PowerNow Daemon v0.90, (c) 2003-2004 John Clemens powernowd: Found 1 cpu: Couldn't open file: No such file or directory Couldn't open file: No such file or directory Couldn't open file: No such file or directory couldn't open govn's file for writing: No such file or directory Couldn't get per-cpu data: Illegal seek PowerNowd encountered and error and could not start.
