This snipped removes a specific fields from the fieldsets. This is very useful to leave a field 'out' in the admin, likewise: 

def get_fieldsets(self, request, obj=None):
    fieldsets = super(BlaModelAdmin, self).get_fieldsets(request, obj)

    if not request.user.has_perm('change_blah'):
        remove_from_fieldsets(fieldsets, ('blah',))
