All your problems will be solved when the bug I referenced in the
first place is fixed. Ie., you will be able to use 'from module import
*' for a module in the same directory as your PSP page.

If you can't wait that long, do not put your modules in the same
directory as your .psp files, put them in a directory which is outside
of your document tree. Then use PythonPath directive to add that
external directory to the standard module search path. By doing that
the mod_python module importer will be skipped and 'from module import
*' will work for you.

Note, do not add the document directory itself to PythonPath as you
shouldn't overlap mod_python module path and standard Python module
path.

Also note though that by putting them in a directory outside of the
document tree and thereby using the standard Python module importer,
those modules will not be candidates for automatic module reloading.
Thus, whenever you make a change to them, you will need to restart
Apache for the change to be picked up.

The only other hack I can suggest is to do something like:

  module = apache.import_module(module_name)
  globals().update(module.__dict__)
