When I run it I get this msg with current svn Mesa/dri/ati-video

  Try R300_SPAN_DISABLE_LOCKING env var if this hangs.

File r300_vertexprog.c function t_dst_index line 184
Unknown output 3

Any idea if this would hit performance? It's a lucky shot but I've seen 
performance related posts on the list related to vertexprograms.


How do I disable software fallbacks as seen in Rune Petersen's patch? 
with an environment var?
