Let me know if you need any other log. Ok, your TV only reports 1080i as a mode (at least that's the only thing your kernel can decode). The i915 driver then rejects it because it's interlaced (we unfortunately do not yet support interlaced everywhere we could). Which leaves you with no modes, so as a fallback the kernel just adds a bunch of default VGA modes which your TV can't cope with properly. Your TV likely sends a CEA block with some HDMI default modes set. Since linux-3.3-rc1 (to be released in a few days) we should be able to decode that. Can you grab the latest -linus kernel git and try that? Also, can you add a short list of the modelines you've manually added that work with your TV?
