Can you double check that the parameter change took effect with the following
command:

> sudo cat /sys/module/i915/parameters/enable_fbc

If it says "1" then you should open a new bug report as any screen corruption
is not caused by fbc in that case.

If it says "0" then something is wrong with the way you are setting the
parameter.
