I would look into startups. Many startups are willing to have a more engaging conversation with someone, and take into consideration 'non-traditional' work experience. By demonstrating what skills you do have in this area (and being willing to work for a little less than the going rate) -- you should be able to get involved in a high-tech venture.
This would give you resume experience, expose you to the new technologies you desire, and if you learn and grow with the startup, it would be a great environment to grow in responsibility quickly as they grow.
