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.

It turns out all the failure patterns I've thought I've seen so far up through .38.x are moot.
However, now on .39-rc, the KMS'd console is stable, and starting X makes it bad again.
It there anything useful I can pull from any logs on the startup of X? Either from the X server, or the kernel. Last time I looked at the drm log from the kernel It was unreadable to a mere mortal, but I hope you guys can point me to what debug knobs to enable to get a good view of the interesting parts (How does one start a minimal X, btw? "xinit" gives me an undecorated xterm with the jitter. Can one start something more minimal?)
Currently running today's git xorg-server and xf86-video-dri.
