I finally found that the problem goes away if I downgrade
xserver-xorg-video-ati and xserver-xorg-video-radeon from 6.14.1-1 to
6.13.1-2, which is the version from Stable.
B.t.w., it did pull a bunch of other downgrades with it.
Your explanation about disabling modesetting looks interesting enough
to have a look at one day (thanks!), but that does not appear to be at

That does not make mouse + keyboard work either.
At boot time I see this line:
startpar: service(s) returned failure: udev... failed!
This line does not appear when /run is not present.
