--- Comment #8 from Rafał Mużyło galtgendo@o2.pl --- ...minor correction: that r300 was for the non-galium driver (that was removed awhile ago), but it seems that the logic in that commit was incorrect, so the "hack" from that attachement seems to be a logic fix and most likely *is* valid for radeon/radeon_state.c.
