great! it works:

sensors excerpt :

coretemp-isa-0000
Adapter: ISA adapter
temp1:       +62°C  (high =  +100°C)                     

coretemp-isa-0001
Adapter: ISA adapter
temp1:       +64°C  (high =  +100°C)

how do I find that out ? I mean sensors seem to work but how do I know
which CPUID+version I have ?

$ cat /proc/cpuinfo  | grep stepping
stepping        : 8
stepping        : 8

Thank you *very* much!
