Uuups - update:

The version without CPUTYPE?=opteron made just a boo-boo. It seems
that this one is more "stable" but still hangs itself to dead.

I tried to bring traffic on the loop (ping), the replies got
lost:

atest# netstat -I patm0 1
            input        (patm0)           output
   packets  errs      bytes    packets  errs      bytes colls
         1     0         92          0     1         92     0 
         1     0         92          0     1         92     0 
         1     0         92          0     1         92     0 

(the input ist the "ping", the tried (but failed) output should be 
the pong). I now deleted the settings (atmconfig natm delete ...) 
and tried to re-set the Network configuration:

atest# ifconfig patm0 192.168.254.2/24

=> Boom

Kernel is aboslutely dead, not responding to whatever (keyboard,
acpi-power-down events, ...)
