This code piece is not the culprit. In 2.6.16, the mechanism of setting up group power for allnodes_domains is wrong(which is actually causing this issue in the presence of dynamic sched groups patch) and the mainline has fixes for all these issues.

Basically SLES10 has to backport all these patches:
sched: fix group power for allnodes_domains sched_domai: Allocate sched_group structures dynamically sched: build_sched_domains() fix
