I voted "Yes! make separate lists for all three sections" because a lot of users have questions about what "actually" works or don't work under 7.
I think it would also be a good idea to include the download links for the Direct X files, seeing that this is the most commom problem why a lot of games have issues.
Download details: DirectX Redist (August 2009)
Download details: DirectX End-User Runtime
just my two cents
