Instead of RADEON(0) we see FBDEV(0), instead of 24bbp, only 16bbp is
being used.  Only 1536kB of video memory is being used and the screen
size is set to "Virtual size is 1024x768 (pitch 1024)".

I don't know enough to determine what is causing these differences,
let
alone how to correct the problem.  If someone else can figure out a
solution I would be most grateful.
Most likely missing firmware as others have suggested, check dmesg and
grep for radeon and/or drm.

I will install firmware-amd-graphics as soon as I get a chance (probably this evening) and report back. Meanwhile, Felix says that he never received my post with the full logs and others seem not to have received them, either, by what they have posted. For the sake of keeping all of the information available for the future, I will post them at that time, as well. Should they be sent as attachments, or inline. I sent them as attachments last time. Could that have been the problem?
