Dunno why the numbers are different, but it's now 1738 in 2.6.5-mjb1 ...
I wouldn't have thought we'd inserted that much since then. anyway, it's
this:
/* Tally up the load of all CPUs in the group */
cpus_and(tmp, group->cpumask, cpu_online_map);
WARN_ON(cpus_empty(tmp));
in find_busiest_group. Which makes sense I guess, but is very ugly.
