here are the screens of some issues with my HD4650:
the color change done to close/far field (gren/red/darker):
..you are running Ubuntu 8.04LTS with ATI's proprietary
fglrx, or is there a "Catalyst" driver too?
Have you tried a recent Live CD or Live USB with
radeon, radeonhd and fglrx on your box?
..x.org's docs trails development a bit, radeonhd was supposed
to support the newer cards better than radeon, but radeon looks
like it's winning the race: ;o)

On ubuntu karmic i use the provided fglrx driver (9.12) and on windows
xp both the 9.12 and 10.01 catalyst driver (the "hotfix" version) (but
didn't test windows for a while).
my main OS is a debian sid, with a git radeon, but glsl are not
implemented yet (rv730) .
glxinfo give me:
OpenGL shading language version string: 1.10
and fg run too slowly, but kompiz is fine.
a temporary fix is to remove the "gl_FrontMaterial.ambient" part in 3
files, and so i have no more dark/blue/green super FX, but don't ask me
to say why :) .
that works with the crop and landmass.
here's the diff:
