Well, I've just been following this thread and I choose to make a small
patch against your O1 int to export the scheduler tuning knobs via
sysctl. This patch will create /proc/sys/kernel/sched_tuning and expose
all the knobs, sou you guys don't have to recompile and reboot just to
change, say, max_sleep_avg. Don't know if anybody will find it useful,
but at least it doesn't hurts :-) 
It should apply cleanly against plain 2.5.73, altough I didn't tested.

wrt your patch, I must admit I didn't feel any difference from vanilla
2.5.73, but this feeling isn't much scientific 8). I will do some
serious tests tomorrow if I find any time.
