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
