If you want support for a "new" processor, like ARM, you need to have the underlying kernel support first. If you are targeting Linux, you should have a look at the "perf_counters" support, which is new as of Linux 2.6.31 (which is not quite released yet). There are currently implementations for x86, Power, and recently some SPARC support has been added. I don't know if anyone has started on ARM support yet.
