Hi Dieter,

for the open source driver you don't need any of those adapters. They 
are only used by fglrx to identify the "original" adapters that came 
with the board.

So the poor little one which came with the gfx card should be 
sufficient, but if you want to use fglrx + some other adapter you might 
run into problems.

Christian.
