Not without hacking. You would need to allocate a profiling buffer on module loading, and extend x86_do_profile (or the equivalent on the platform you're using) to search a table of these secondary buffers.
The profiler puts out-of-bound EIP values into the last histogram slot, so you see at least when your module runs @)
