One of the articles on ThinkWiki says that fglrx+powerplay provides
better power savings than rovclock/radeon.

Shameless plug: I wrote a script that should help you determine the
power drain of various configurations:

    http://thinkwiki.org/wiki/Script_for_monitoring_power_consumption

The main thing the script lacks is some nice reporting feature.  It
currently just captures a bunch of information in a list() of dict()
objects (in Python).  Fortunately, this is quite human-readable.
(Adding such a nice summarizing capability to that script is on my
ever-growing TODO list ;)

Hope that helps!
