This fixes lighting bug 26809 with NWN on my rv250, but R200 untested as yet. To correct the section size mismatch, add the following before the BEGIN_BATCH_NO_AUTOSTATE() line; dwords += 2; Thank you very much for finding this three year old radeon rewrite bug. I assume you discerned this from cmdscl used for LIT_CMD_1 versus cmdvec used for LIT_CMD_0?
