Hi,
I'm getting the following message from lspci on my K8 machine:

Note the warning about "Possibly incomplete decoding" which stems from the fact that the processor mentions HT revision 1.02 which is the last non-public revision. Every revision from 1.03 and beyond seems to be publically available. Now the big question is: Can we decode HT 1.02 like HT 1.03 or have there been fundamental changes in between? I'd like to create a patch for PCIutils (lspci) so we can have full info without a warning message.
