tpm-static.fs is now gone and I replace all accesses to vTPM related 
functions through this 3-line find-node sequence above.

A detail is now that with the global vtpm-debug? gone I now have 
vtpm-debug? again once in the code for /ibm,vtpm and once in 
/vdevice/vtpm. Do you have any suggestions ?
