I think I found the problem. The hardware already makes the right decision
based on the FACE_bit. This code in r700UpdatePolygonMode actually reverses it
when using clockwise winding:
if (ctx->Polygon.FrontFace == GL_CCW) {
f = ctx->Polygon.FrontMode;
b = ctx->Polygon.BackMode;
} else {
f = ctx->Polygon.BackMode;
b = ctx->Polygon.FrontMode;
}
Changing it to:
f = ctx->Polygon.FrontMode;
b = ctx->Polygon.BackMode;
seems to fix it and render everything correctly.
