This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- lucid' to 'verification-done-lucid'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

And there is a secondary problem that the Thinkpads have the chip in an ACPI configuration that, while standard, eludes the kernel's autoprobing. Enterprise customers already relying on the TPM chip cannot move to newer laptops with the new iTPM chip because it is not supported by Linux. David Smith (~dds) has done a lot of work in this area. There are two kernel patches involved. The first has been merged into the mm tree. The second is being reworked. 1: http://marc.info/?l=linux-kernel&m=125381794406624&w=2 2: http://marc.info/?l=tpmdd-devel&m=125264268716691&w=2 Need to track these and see if they have hit the 2.6.32 tree.
