I finally got time to try this, and it didn't help much.  Changing all
the packages to dot notation works fine.  I have added the
toolkits/__init__.py file.  Setuptools warns about not having
declare_namespace in the init files.  I have added this:

try:
    __import__('pkg_resources').declare_namespace(__name__)
    print __name__, __file__
except ImportError:
    pass # must not have setuptools

to __init__.py in mpl's and basemap's matplotlib and
matplotlib.toolkits module, hence in 4 places.
Upon starting python I get this output:

matplotlib /usr/lib/python2.4/site-packages/matplotlib-0.86.2cvs-py2.4-linux-i686.egg/matplotlib/__init__.pyc
matplotlib.toolkits
/usr/lib/python2.4/site-packages/matplotlib-0.86.2cvs-py2.4-linux-i686.egg/matplotlib/toolkits/__init__.pyc

So the basemap declarations are never being reached.  Where should I
go from here?
