OK, better luck this time...
I read about no stripping and some compiler flags and re-compiled
X, DRM and xf86-video-ati (again...).
I also found the way to turn on the debug of the drm module.
So here it is, this is what gdb shows while X hangs:
(I caused the SIGINT with ctrl+c in order to see where X hangs...)

As for drm kernel module, these are the debug messages I got:
a lot of these message loops-
