Actually, the post I am referring to was about 6 months ago (which
still doesnt mean it made it :-(.  Here it is again:
"""
import win32api, imp, sys
def magic_import(modulename, filename):
	# win32 can find the DLL name.
	h = win32api.LoadLibrary(filename)
	found = win32api.GetModuleFileName(h)
	# Python can load the module
	mod = imp.load_module(modulename, None, found, ('.dll', 'rb', 
      imp.C_EXTENSION))
	# inject it into the global module list.
	sys.modules[modulename] = mod
	# And finally inject it into the namespace.
	globals()[modulename] = mod
	win32api.FreeLibrary(h)
try:
	import pywintypes
except ImportError:
	magic_import("pywintypes", "pywintypes15.dll")
try:
	import pythoncom
except ImportError:
	magic_import("pythoncom", "pythoncom15.dll")
