It was traditionally done like that on powerpc to provide a nice console
experience and suspend/resume support on laptops.

Presumably, the radeon driver is loaded by udev because it declares that
it supports your GPU. It could still be used by older upstream versions
of xserver-xorg-video-radeon and libgl1-mesa-dri, but the current
versions only support KMS anymore.
I believe I answered your other questions in my previous two e-mails.
