I believe that the relevant stuff have been merged into libdrm master.

Well no ;-) Debian libgl1-mesa-dri does not include r600 module
(Debian kernel does not yet include DRM driver for r600), so you have
to rebuild mesa.
Also note that current git kernel (and 2.6.32) contains the needed DRM
bits (more changes and fixes can be found in airlied's tree:
http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=summary,
branch drm-next)
