powernowd is much better at throttling CPU's (not just AMD's, but
Intel's too) the cpufred. Laptop-mode-tools can also help extend battery
life by spinning down the HDD. You might want to look into acpid or
powersaved for general power management.
The major difference that windows has over linux for power management is
ajusting the power output to the LCD screen. I have yet to find any app
that accomplishes just that.
