One imho major problem with the new scheduler is that its new sched_yield breaks programs like OpenOffice, who rely on the old sched_yield behaviour. With new scheduler and 2.5 yield OpenOffice can be completely starved just by a kernel compile because sched_yield kills all its time slices.
I don't think a stable release should break programs in such a way.
