thanks, i've added this to latency.c. You can find my current snapshot
at:

  http://redhat.com/~mingo/private/voluntary-preempt-2.6.9-rc1-bk12-R9-A6

there are alot of changes - perhaps one of them fixes your LATENCY_TRACE
problem - but the likelyhood is low, for me LATENCY_TRACE worked fine on
amd64 even with -R8.
