in 2.6.24-rc1 kernel, The /proc/cpuinfo display is wrong.
One issue is every processor id appears to be 0.
That is because smp_store_cpu_info will set cpuinfo_x86->cpu_index to cpu id then call identify_cpu identify_cpu will call early_identify_cpu which set c->cpu_index back to 0.
This patch set cpu_index after identify_cpu to fix the issue.
