@pega-1 : It can have "no officialy / top secret" supported hardware that works. For example :

Radeon 9500 pro are not listed but works (ok it's like Radeon 9700 but not the same name).

On this grab (http://www.exception-dev.de/mos/g5gfxcard.png), GraphicBoards say "Radeon 9600 / X1050" so Radeon X1050 must works even if there are not listed too.

Dev can forget a beta driver at release too :)

So i'm happy to say that i'm a bit silly to test unsupported graphic card when new MorphOS release come out :)
