Try booting with radeon.audio=0 on 2.6.38rc, some TVs have problems with the hdmi packets we send by default. disabling audio will treat the hdmi like dvi.

You seem to be on to something there. radeon.audio=0 removes what appears to be all of the jitter. I say "appear", because during my many test runs today, I've come across moments where my brain goes "wasn't what I just noticed on the TV something abnormal?" Both in fb mode (post KMS), and in X11. It's definetly improved from useless for family use, to perfectly ok though.
I was too early on this one. Yesterday (.38) , and today (38-rc8), are both jittery in post-KMS fb mode and in X, even though I use radeon.audio=0.
A power cycling of the TV stabilizes it though.
I'd be more than happy to test out any patches or ideas you might have.
