There's no real "list". U Penn has a list, you can simple Google it, but it is by no means comprehensive. Some hospitals participate in Versant's New Grad program. If you go to Versant's website, they have a map of all the hospitals that participate in their program. It's basically just Google, work of mouth, and research. Good luck!
Since these programs only exist at the 'whim' of CFOs who may decide to axe them at any time. . . there is no ongoing guarantee that they will be available. So, any listing would undoubtedly be obsolete by the time it was completed. FYI, even if an organization has no formal 'residency', that does not mean that they do not have effective processes in place to hire new grads.
