I'm a current PM, previously a developer for a number of years. Here's what I would do:

Create a portfolio of side projects / sample applications in whatever language /framework you'd like to work with. You'll learn something, and have something to talk about in interviews. Then the interview process for a developer position is easy: show them what you've done and talk about how you built it. If your skills and approach are a good fit with the company, they'll hire you.

Another idea: create a profile on oDesk / equivalent and take small paying programming jobs. They may only pay $20, but you can gain experience, contacts, and credibility.
