You can also have a look at the EMSCB project:

On the website you can download a demo CD which contains a very simple TPM 
client application (it shows you some basic information about the TPM like 
version number, public key, and you can get random numbers from the TPM). The 
source code is also available.

More applications on L4 are currently under development in the EMSCB project, 
and as Bernhard said, in the OpenTC project.
