The TPM RNG task is probably best done in a user space process, which might also do other things like pulling environmental noise from the sound card's microphone, etc.
The problem is finding someone with the skills, time, and energy to create the appropriate user space daemon. All of the kernel interfaces already exist; it's just matter of implementing the user space support.
