well, the radeon driver for me works with compiz-fusion and kde4 (either
emerald or kwin-decorator-4) and is fantastic. also drm, exa and 2d video
playback is fantastic.
the only drawback is the following:
you'll need to use live ebuilds from the x11-overlay. i've been with them
for about  6 months now and i can tell you that everything works very well
(no instability or similar issues).
before starting to use them i'd advice you to tell me what board you have
and, since probably is equal to one of my 2 laptop boards (x200m rs480 or
x12xx, rs690) i can pass you all the configs to have everything working. a
full live xorg build (a partial one would cause you some instability issues)
that includes xorg-protos, xorg-libs, xorg-server, mesa, drivers would take
about 3-4 hours, but you might be forced to reinstall all kde4 after that
(this happens often after a new rebuild of xorg-git) and so you'll still
need around the old 3.5 installation. in fact i have compiz enabled by
default on that one and i start it manually on kde4 since sometime it has
some issues on startup with setting the kwindecorator4.
if you'll tell me that you'll be willing to use this method i'll prepare a
walkthrough of everything you'll need to install, in which order, what
overlays you'll need to use (you'll want desktop-effects for compiz-fusion)
and what options you'll want to enable and use on the board. to do
everything in a fine way you'll probably take about one day of work
(including xorg-modular rebuild and kde4 rebuild).
also i reccomend the setup of portage-tmpfs on /tmpfs so that the
compilation speed would drammatically increase.
let me know if you're interested. if you're not then you won't be able to
use any desktop effect (not on kde3.5 or on kde4) and since i find out some
compiz effects very PRODUCTIVE for business environments (i didn't
understood this until i've used compiz for about a week) it would be a shame
not to use it.
