	Please note that the original card firmware had all powerstates
the same, i had used rbe (http://www.techpowerup.com/rbe/) to change then
to the current frequencies. In that app, the powerstate 1 is called
battery and the powerstate 2 is called performance. 

	I can switch the two and reflash, but to me seems logic that one
can manually choose what powerstate to use if needed, just like the 
powerlevels (excluding the middle powerlevel problem)

	Here is the output:

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI RV 630 XT AGP [Radeon HD 2600 XT AGP] [1002:9586] (prog-if 00 [VGA controller])

Thanks in advance.

Naturally the common people don't want war... but after all it is the
leaders of a country who determine the policy, and it is always a 
simple matter to drag the people along, whether it is a democracy, or
a fascist dictatorship, or a parliament, or a communist dictatorship.
Voice or no voice, the people can always be brought to the bidding of
the leaders. That is easy. All you have to do is tell them they are 
being attacked, and denounce the pacifists for lack of patriotism and
exposing the country to danger.  It works the same in every country.
