Hmm, except for some sched policy setting problems on NPTL, I don't
see bigger problem than 2.4+preempt kernel. For some people,
2.4+preempt might work _casually_ better than 2.6, but it can happen
vice versa.
Shouting "DON'T USE 2.6" isn't a good solution. Though, we need to
inform to "set LD_ASSUME_KERNEL as a workaround"...
