There is a several bug in the unit inicialization code which afect more
units not only Graph. Look at this bugreport:
http://www.freepascal.org/mantis/view.php?id=7338

You could to try use my modified unit Graph
http://www.laaca.borec.cz/graph.zip
which works for me but the inicialization bug in FPC 2.0.4 makes this
compiler virtualy unusable.
