I suppose any X server needs access to the framebuffer, keyboard and
mouse. I've solved these things so that the device nodes needed for X
server are owned by group xyz and the Xserver binary is sgid xyz. This
is not very good solution. What I would like, is login or xdm to chown
the device nodes to the user who logs in.

It's the same problem on all archs but IMHO the worst solution is to
run Xserver suid root. I've said this before, but here goes again..
Xservers tend to be huge programs and huge programs tend to have bugs
and buggy suid root programs can crash the system. Who knows, maybe
the mysterious crashes I've been having for a long time were caused by
my xlock which was suid root.
