For a PCIE card just don't configure AGP
  CONFIG_AGP=n
  CONFIG_DRM=y
  CONFIG_DRM_RADEON=y

But the Xpress 200M is not yet fully supported in testing with the open
source Xorg driver "ati". In /var/log/Xorg.0.log I get among others

   (II) RADEON(0): Direct rendering broken on XPRESS 200 and 200M

So no 3D-acceleration (compare "6. IGP" on
http://dri.freedesktop.org/wiki/ATIRadeon and
http://dri.freedesktop.org/wiki/Radeon200M). The AMD/ATI driver "fglrx"
has 3D-acceleration but its closed source.
There is a petition list on this topic:

Maybe you want to join it?
