The misery begins as soon as you try to switch from X to console either
by Ctrl-Alt-F1 or induced by system shutdown

the monitor goes black and the sysem will not react to any input not
even to SysReq Keys

How about ssh? Can you still login via shh?


nope
all running ssh-sessions to that machine freeze the moment it tries to
switch to console.

I had some tail -f's running in ssh-sessions on
/var/log/{debug|messages|Xorg.0.log}
All I see is the "shutdown" Broadcast message and Log-entries. Nothing more.


after about a minute or so the system powers off and immediately on
again to boot up normally (with the usual warning about HDs not having
been unpountet properly)

I have no idea so far as to where I should start investigating. The logs
don't show any abnormality as far as I can say.

Maybe something related to the VGA card driver or KMS... is there
something interesting in the logs ("/var/log/syslog" or "/var/log/
Xorg.0.log")?


No, at least nothing that seems even vaguely related to the crash.
