We tried and with 2.6.35-rc4 we could boot without video=. First good news :)

with radeon.agpmode=-1, we could start X server (no black screen),
with both radeon.modeset={0,1}. In all cases, Xorg works fine, except
when we try to load an OpenGL application (like glxgears), Xorg
freeze, we could move only the mouse, we couldn't switch to a backup
console. Same situations with glxgears in both modeset=0 and =1. In
the log (Xorg.0.log) we have found:

Do we need to compile mesa, ati-dri, x.org and xf86-video-ati from git?
Many thanks
