Xorg.0.log shows this warning: (WW) RADEON(0): "RightOf" is not a valid parameter for Option "CRT2Position" (II) RADEON(0): Valid parameters are "RightOf", "LeftOf", "Above", "Below", or "Clone" (II) RADEON(0): Except for "Clone", the parameter may be followed by an integer. i think rightof == rightof, but whatever!
this was fixed a while ago in xorg cvs. please try a newer version.
