Brian, can you tell me what are the differences in swrast component between the
7.11.2-1 mesa release version and the 8.0.x release ?

we know that swrast runs without problems in 7.11.2-1 mesa version with blender
and an old ati radeon card ( rv250, rv280 cards ),

but something in the 8.0.x mesa release has changed in the "swrast component",
if we can locate these new lines in the source code then we will find probably
the culprit,

maybe a new onpenGL instruction who is not supported by old card like rv250,
rv280, don't forget that radeon 9000 card ( rv250 ) only supports opengl 1.3
version,

I need some tips in order to debug this problem ( I'm a newbie in debugging
opengl/multimedia software )

thanks
