it's only limited support, because I don't have a radeon/ctpci to test myself and optimize radeon acceleration.
I'm using my firebee for the developpement, and it's hopefully compatible with radeon.
but since the firebee xbios lack a lots of video features, no blitter acceleration, and no double buffering support, the true color version is rather slow and not optimised.
but I can't do better with the current version of the firetos. (and no motivation to buy a radeon/ctpci..)
