Well you live and learn.
Yup, we should make the toy sched_clock() match the fancy ones.
otoh, sched_clock() should do the INTITAL_JIFFIES offsetting as well, because there are probably callers of sched_clock() who are buggy in the presence of sched_clock()-return-value wraparound.
otooh, sched_clock() wraparound takes nearly 500 years so we can afford to wait until linux-2.7.x to fix this.
I'll go off and find your original patch. This was all a difficult way of writing the changelog ;)
