there's also Peter's other patch upstream since yesterday (and included 
in -rc3) which should solve the same problem:

| commit c1955a3d4762e7a9bf84035eb3c4886a900f0d15
| Author: Peter Zijlstra <a.p.zijlstra@chello.nl>
| Date:   Mon Aug 11 08:59:03 2008 +0200
|
|    sched_clock: delay using sched_clock()
|
|    Some arch's can't handle sched_clock() being called too early - delay
|    this until sched_clock_init() has been called.

so i'd be mighty surprised if this dual firepower of commits didnt at 
least weaken this bug somewhat! ;-)
