Comment # 15 on bug 99843 from dan@jerber.co.uk

I was reading about the R600 driver and came across a TODO page that suggested
testing using piglit.

I downloaded and compiled this. I ran the "shader.py" test and it gave the
following results:

skip: 26496  Pass: 6567  Warn: 2  Fail:496  Crash: 5

I'm not sure if piglit is a good measure on this but the number of fails seems
very high.
