Radeon 9600 and 9800 based cards are a little tricky on AmigaOne's as the AmigaOneXE only supports 1x and 2x AGP compatible cards. The reference cards from ATi does support 2x but many third party manufacturers have discarded the support for 2x and these cards only works with motherboards that supports 4x or 8x speeds.
I wouldn't recommend testing a card that you are not certain if it supports 2x as 2x cards run on 3.3v. 4x cards run on lower voltages and could be damaged by running on 3.3v. If you are unlucky your entire motherboard might become fried.
Most motherboards have a type of AGP bus in which only a certain type of card fits. For some reason the AmigaOne have a universal AGP bus which makes it possible to insert any AGP card no matter what voltage it supports.
