System configuration :

- radeon 9000 AGP ( M9, rv250 )
- laptop pentium 4 2.4 Ghz 1.25 Gb ram
- archlinux 32 bits

Step to reproduce the bug

- mesa 8.0.4 release ( but the bug occurs also with the git version )
- a graphic card who uses the r200 driver 
- install piglit ( git version )
- run the glean test "fbo" in piglit :

./piglit-run.py  -t "glean/fbo" tests/quick.tests results/quick

the glean/fbo will fail with these error messages :
