well, Plone 2.5 is already using GenericSetup to create all of the ATCT 
types; the ATCT Install.py file never gets called.  we should probably 
put deprecation warnings in the installTypes method.

GenericSetup profiles still trigger python code which actually does the 
FTI creation.  for migration we'll still have to do this 
programmatically.  the failure of the migration, then, is not due to 
GenericSetup so much as it is changes in the FTI creation code.

the best thing to do is to examine the 
Products.CMFCore.exportimport.typeinfo module, which contains the 
GenericSetup node importer that actually performs the type creation.

remember is far from complete (or even working), but it uses an 
extension profile to install itself:

http://svn.plone.org/view/collective/remember/trunk/profiles/default/

there are also several extension profiles defined in the CMF itself, 
CMFUid contains one, CMFCalendar as well, IIRC.
