[PATCH] Enable microtiling for R200 if DRM >= v2.x
Mesa only checks the minor DRM version number when deciding whether to enable texture microtiling. This would imply that microtiling hasn't been enabled since the 2.6.30 kernel.
The HyperZ check for R200 does examine that the major DRM version number, but completely disables HyperZ for DRM v2.x. I don't know if this is intentional or not.
