XVideo on radeon mobility HD 5470

Firmware for your card has been released, but userspace acceleration code is still under development. It's the acceleration code to *implement* Xv on your GPU that you're missing. 

When the acceleration code appears, you'll also need 2.6.35 or higher kernel drive to support it.

Subject: XVideo on radeon mobility HD 5470

I have a Radeon Mobility HD 5470 in my laptop, but XVideo does not work.
xvinfo reports there are no adaptors present.

Xorg.0.log reports this:
(II) AIGLX: Screen 0 is not DRI2 capable
(II) AIGLX: Screen 0 is not DRI capable
(II) AIGLX: Loaded and initialized /usr/lib/dri/swrast_dri.so
(II) GLX: Initialized DRISWRAST GL provider for screen 0

I am running kernel 2.6.34, xorg ati video driver 6.13.0 and I have the firmware package installed for DRM (Debian sid, pkg firmware-linux-nonfree).

I think the problem is that this card is too new and there is no firmware for it yet. All the firmware in /lib/firmware/radeon is for R/RS/RV cards, but my card is a CEDAR (post-RVxxx naming). There doesn't seem to be any firmware for it, and the linux kernel drm does not seem to try to load any firmware.

Other things seem to work OK. I've got KMS working, fbconsole on radeonfb. I don't know how well 3D works, since I dont use it.

Is this something I will just have to wait until ATI makes firmware available before I can get XVideo support? Can I tweak anything to get it going? Have I got it all wrong and my problem is somewhere else?
