No, because AVGA cards are based on ATI chipsets but don't use a standard ATI driver.
Why would you want to use Powerstrip (PS) on an AVGA card anyway?
If you want to use PS, try getting yourself a card with an ATI Radeon 9250 or 9550 chipset. That is what the AVGA cards V1 and V2 are based upon, and PS works well with them (as does Soft15khz, which is very nice and easy to use by compairson with PS).
