I have done a quick search of the SL list archives for TPM without a 
positive result.  Boot message:
a tpm error (7) occurred attempting to read a PRC value

There is a set of packages that deal with TPM:  tpm-tools and others.

On the web, I have found that one method to deal with the diagnostic 
simply is to blacklist  tpm
echo blacklist tpm_tis > /etc/modprobe.d/tpm_tis.conf

Is TPM vital to a standalone Internet attached workstation?  Will 
tpm-tools allow one to accomplish the effect of
the blacklist?

Note the machine does boot and run.  However, diagnostics normally 
should not be ignored.
