cross-cpu balancing with the new scheduler

Is it possible that the inter-cpu balancing is broken in 2.5.2-pre11?

eatcpu is a simple cpu hog ("for(;;);"). Dual CPU i386.

$nice -19 ./eatcpu&;
<wait>
$nice -19 ./eatcpu&;
<wait>
$./eatcpu&.

IMHO it should be
* both niced process run on one cpu.
* the non-niced process runs with a 100% timeslice.

But it's the other way around:
One niced process runs with 100%. The non-niced process with 50%, and
the second niced process with 50%.
