Window Manager Decoration garbage w/ head everything + KMS

[Andrew Chant]

Hey,
 Recompiled everything head (xserver, ddx, mesa, libdrm as of Dec 30)
on 2.6.32.2 on an RS780 and I get really corrupt window manager
decorations (openbox).  Everything else works pefectly though
(openarena, firefox).  The corruption disappears if I don't use
modeset=1 when loading radeon.
