_cpu_count As per metalink, meant for those "exceptional" Operating Systems, where OS does not support a system call so that Oracle can get the number itself.
So normally this value is not required to be set by DBAs. You have to set this when cpu_count is not showing the actual number of CPUs.

I just noticed that there's two parameters in 9.2, cpu_count (which defaults to number of CPUs OS says), but what is _cpu_count? It seems to be independent from cpu_count & defaults to zero on my machine...
