[Knut Petersen]

rendercheck 1.4 has a lot to complain ...

hardware: Aopen i915GMm-hfs
kernel: current linux-2.6 git master
Xorg: current git master
      - rendercheck started directly from .xinitrc
      - no kde, no gnome, nothing but rendercheck
dmesg: clean, no warnings, no error messages
Xorg.0.log: clean, no warnings, error message
i915_error_state: clean
