Hi,

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.
Regards,
Carl-Daniel
