[Summary below distilled from: https://wiki.ubuntu.com/iTPMSupport and
https://blueprints.edge.launchpad.net/ubuntu/+spec/itpm-support]
Contemporary Lenovo and Dell laptops include a newer
[[http://en.wikipedia.org/wiki/Trusted_Platform_Module|TPM chip]] (iTPM)
which is not well supported by Linux.
The fundamental problem is that iTPM doesn't set the TPM_STS_DATA_EXPECT
status bit when sending it a burst of data and the current kernel module
considers that a failure. 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.
[[http://launchpad.net/~dds|David Smith]] has done a lot of
work in this area. There are two kernel patches involved. The
[[http://marc.info/?l=linux-kernel&m=125381794406624&w=2|first
one]] has been merged into the mm tree. The
[[http://marc.info/?l=tpmdd-devel&m=125264268716691&w=2|second one]]
is being reworked.

Need to track these and see if they have hit the 2.6.32 tree.
