I have an instrumented kernel built that should be able to answer that question. 
  While this readme is slightly outdated, gives an overview of the nature 
of the diagnostics provided.

The kernel is a GTA01 kernel at present. If this code might be helpful to you, 
I'll be happy to strip out the GTA01-specific stuff, and build a GTA02 kernel -- 
or just provide the instrumentation in the form of a patch if you prefer that.
