Looks like check_tasklist_locked is in fact GPLONLY on that kernel. That's 
not the case with RH AS 3's stock kernel (or at least mine, 
2.4.21-15.0.3.EL, also ia64):

# grep check_tasklist_locked /proc/ksyms
e000000004989770 check_tasklist_locked_Rsmp_15bb5893

Did sgi do something silly? (is this an altix? I can try AFS on ours if 
so...)
