    Only 2 TPMs I've seen were on pluggable modules... which was fortunate
    because they slowed down boot by 5+ minutes, and broke it completely
    in other cases. Nickname 'kurvitko' (aka useless trash that breaks
    stuff). They are currently lying under my table, disconnected.

    (OTOH they were not on PCI, but on some low-count pin header).
