Hi! I got around to testing with "video=radeonfb:off" on the kernel commandline. What you then get is a completely hanging system when switching terminale (chvt), when trying to stop the login manager KDM or when logging out of an X session. Note that this means that rebooting the system becomes impossible, similarly partitions aren't unmounted properly either.
I also tried activating KMS explicitly then, but that crashes even earlier during boot, even before init is started. The kernel seems to detect that my video card has 256MiB of VRAM, while it only has 32. Some other memory layouts it detects are similarly off. If I find a free hour I'll try to disable KDM and then try without radeonfb, if that is broken, too, or if it is only in combination with X. I'll also try to copy the kernel output when using KMS.
