SE_TCL_OUTPUT_VTX_COMP_SEL or SE_TCL_OUTPUT_VTX_FMT_0?  There isn't even=20
a bit for fog in SE_TCL_OUTPUT_VTX_COMP_SEL in r200_reg.h.  Hmm...

The R200 driver is totally hosed any time when there's a software=20
rasterization fallback (i.e., stencil operations in 16-bit depth mode).=20
  It seems to be t_vertex related. :(
