HowTo: Avoid packages like TPU

With loaddefs.el in Emacs 22, rarely used packages 
like tpu end up showing up in the default obarray operated upon
by mapatoms. Is there a way to avoid this?

I use reflection via mapatoms to find interactive commands that
need to be speech-enabled in Emacspeak, and one unfortunate
consequence is the following:

0) mapatoms finds commands like "set cursor free" from tpu-extras
1) In using reflection, it ends up loading tpu-extras.el (even
   though I have no intention of using tpu)
2) Worse, tpu-extras is evil -- it redefines things like newline
3) And even worse, tpu-current-line (used by the redefined newline)
       raises errors at times when called from display-warning.

In the minimum it would be nice if optional packages that
redefine core functionality such as command `newline' didn't get
accidentally pulled in.
