When you receive an exception, it should check to see if there is
an exception handler registered and if so use that to fake an IPC
to the exception handler.

However, due to the hack being there, it uses the registered
scheduler handler instead.

You are correct, it should use the exception handler not
the scheduler to send the exception IPCs. 

The send_exception_ipc() function is architecture specific, IA-32 seems
to use the scheduler (which is probably wrong) while ARM does the right
thing.
