This is what I do for combined backend/frontend:

1. set scaling_governor for your cpu to "ondemand" (you can also test
"conservative"). you can also use "powersave" but it will use the
lowest cpu speed  (/sys/devices/system/cpu/cpu[01]/cpufreq). you can
also play with scaling_min_freq and scaling_max_freq.
2. set hard disks to sleep after few minutes (5 probably) (hdparm)
3. go to standby after 15 minutes (xscreensaver kills mythfrontend
after 12 minutes and mythwelcome sends the mythbox to standby after 3
minutes)

I change the scaling_governor to "performance" when I play HD files in
mplayer and set it back to "ondemand" after closing mplayer. btb, I
pathced mplayer yesterday to use CoreAVC from Windows and is working
pretty good with less cpu power.
