There were some web pages on this subject that seemed imply that IBM
used a non-standard string-to-key algorithm, and that caused the
incompatibility with Trousers. So if you initialized the TPM using
the IBM Windows drivers, you have to mess around with TSS to get it to
work correctly with Thinkpads. I tried for a bit to try to get it to
work a while ago, but the few things I tried didn't work, and I
eventually lost interest.
