The first attempt was obviously too short fetched as the vital internal format datatypes do not even alias with the current close relatives as I thought in the first place. I gave the cik type radeon an other try this morning and run the oss driver with the two tests. Unfortunately it did not succeed like the gallium software renderers just did. But replacing the R_0282D0_PA_SC_VPORT_ZMIN_0 with 0xBF800000 (== fui(-1)) made the provided piglit test pass. Just replacing the value in this hard way is probably an unappropriate change, but to share what I already saw.
