I just added a link so you can download the version I am currently using with WP 2.9. It may not be perfect but it seems to be getting the job done well enough :)
MoreFields for WordPress History
Are you a long time user of More Fields who is upset that it broke with WordPress 2.8 and hasn’t been fixed yet? Me too.
I needed this for several projects so I hacked my own working version together with help from these folks.

Support, Requests, Etc
Feel free to comment on this page and send along your feedback. However, I’m not getting paid to keep this plugin up to date, I just need it for some projects, so don’t get mad at me if I’m behind the times with it. If you can help make improvements, send them to me and I’ll implement them.
More Fields for WordPress Description
If you are not familiar with More Fields, here is the description of More Fields for WordPress from the original plugin page.
More Fields is a WordPress plugin that adds boxes to the Write/Edit page. These boxes contains input fields, so that additional (more) fields can be added to a post. For example, if you write about books, you can add a box where you can enter title and author, etc. The boxes can be placed either to the right or to the left on the Write/Edit page.
In addition, the new version of More Fields enables you to define post types, which are custom Write/Edit pages that contains a pre-defined set of boxes. For example, you write about books and you write about your holidays, then you can define a post type ‘Book’ and a post type ‘Holiday’ each containing the input boxes relevant to each type of text. You can also set pre-defined categories, tags and templates for each post type.
With More Fields you can:
Add any number of boxes with any number of field to the Write/Edit page.
Add text, textarea, wysiwyg, checkboxes, radiobuttons and select lists as your input fields.
Create custom Write/Edit pages with a pre-defined set of input boxes, custom set categories, tags and templates.
Create archives based on Custom Fields values with custom slugs
Create boxes and post types programatically so that they can be created from within other plugins
List posts based on post type under the Manage menu
Set visiblitiy of a post type based on user level
Set global visiblity of boxes, in addition to the ‘Screen Options’ available for each post type for each user.
