Thanks Baruch,
But, I am still hitting the same issue.
I am using SuSE 2.6.5, but oprofile code looks
similar.
so i manually made that small change from if
(cpu_model > 3) to if (cpu_model > 100), and did a
make modules and make modules_install.
Then inserted the fresh oprofile module.
# opcontrol --setup  --event=CPU_CLK_UNHALTED
 You cannot specify any performance counter events
 because OProfile is in timer mode.
