These modules are now in core in D7.
I think I now understand what you are trying to do, and it is going to be a little more difficult than simply upgrading your site to D7. If I understand correctly, you are taking a D6 module generated by Features, and trying to plug it into a D7 site. Before you can do that you MUST first upgrade the D6 module to a D7 module. You will find more information here. The Drupal API has changed for D7.
If this is only a small site, do a clean install in D7, create your content types manually, and use cut and paste to migrate your content. For larger sites, create a complete working copy on a test bed and do a site upgrade following the instructions found here.
I have done several d6 -> d7 upgrades, and it usually takes two or three tries to get it right. If you do multiple backups during the process, you can restore to a working stage and continue without having to start from scratch if the upgrade fails for whatever reason.
