--- Comment #1 from Matt Turner <mattst88 at gmail.com> ---
I think this was fixed by this commit:

commit f95733ddb7fff0af923fce3a07ebef78fa3139a4

    i965: Respect the no_8 flag on Gen6, not just Gen7+.

    When doing repclears, we only want to use the SIMD16 program, not the
    SIMD8 one.  Kristian added this to the Gen7+ code, but apparently we
    missed it in the Gen6 code.  This patch copies that code over.

    Approximately doubles the performance in a clear microbenchmark from
    mesa-demos (clearspd -width 500 -height 500 +color) on Sandybridge.
