[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.
