There are TPMs exactly for this. Not very popular, though.

  These sound awesome. Wikipedia says many laptops have them. Is this true? If so, how can I detect one on Linux?

    There are tpm kernel modules and tpm-tools package (in Debian, for example). Also sometimes device must be turned on in BIOS Setup.

      And all of the recent Mac laptops have them. You need a special driver -- look here for a good writeup: http://osxbook.com/book/bonus/chapter10/tpm/ http://osxbook.com/book/bonus/chapter10/tpm/
