Okay, so I think your original problem is because the Xorg fbdev driver
uses the colour depth from console by default, and I guess the login
manager you're using can't deal with that. You may want to report that
against the login manager package, but you probably want to use a higher
colour depth anyway. So you need to change it, either for console as
you've been doing, or just for X in /etc/X11/xorg.conf or by having the
login manager pass -depth XX on the Xorg command line.

Right, to use radeon KMS, you need to disable radeonfb with
video=radeonfb:off on the kernel command line. That should give you at
least 2D hardware acceleration, but suspend/resume won't work.
