Your Xorg log shows i915_dri.so is properly loaded and drm was opened. Yet glxinfo shows you get software rendering. That looks like a permission problem with /dev/dri/card0. Permissions are handled via ACL and the ACL should be set by udev in Karmic. However, your udev log does not show any ACL at all (there should be lines like ACL_MANAGE=1).

- check if udev-extras is installed (that contains the acl handling and rules)
- check with getfacl /dev/dri/card0 if your userid has rw permissions on /dev/dri/card0 and check if there is a + sign in the permissions mask
- run the command devkit -s drm and check if it mentions ACL_MANAGE=1

Please post the results of the getfacl and devkit commands to this bug.
