that also works, but think changing the radeon_ram_size will not be the best 
way, e.g. confusing users not showing full ram size of the card.

good point, but what is the min value of ram that must be left for the frames? 
seems that shifting 5MB is enough. so may be it would be the best when the 
shift is only applied if there are more than 8MB ram left.

might be, but i have no other idea how to detect if fglrx is used for the 
xserver... :(
