It doesn't work...  I cannot use version_id 0 in tpm_tis or in 
tpm_emulator. For tpm_tis I get the error 'Missing section footer' upon 
VM resume and for some weird reason it doesn't allocate the blob buffers 
when reading them in tpm_emulator. I get a NULL pointer instead. So, we 
are better off with version_id 1 here... The CRB seems to work as is.
