Try:

        echo 40      500     64      256 0 >/proc/sys/vm/bdflush

once you want to return to the old behaviour:

        echo 40      500     64      256 500 >/proc/sys/vm/bdflush
        killall -CONT kupdate

With this below additional patch you can avoid having to modify the
bdflush sysctl and you can simply killall -STOP or killall -CONT kupdate
to wake/stop it (as you can just do in 2.4.x).
