You say hiring is weighted against older generalists, but in your resume you call yourself a generalist on the second line and call yourself OldCoder everywhere. Maybe you aren't doing yourself any favors?
The best job hunting advice I ever read was from Nick Corcodilos' book Ask the Headhunter: Reinventing the Interview to Win the Job. The takeaway is that companies are trying to make money, and if you can demonstrate how you'll contribute to the bottom line, they'll have no choice to hire you. If the interview or recruiting process isn't giving you a chance to demonstrate that, then you need to restructure the interaction.
