It should be noted that one of the prime purposes of the Trusted Execution Technology (TXT), aka LaGrande Technology is for DRM enforcement systems that can be nearly uncrackable.
It can be used for other things, such as restricting who can look at your medical records (basically, the same technology that prevents you from breaking the DRM on say, a high-definition movie from Hollywood) can also be used to enforced who can look at your certain records, such as medical records in a highly secure and non-circumvental fashion.
Ross Anderson was one of the first to write about these concerns, over five years ago:

It's interesting that his 2003 document was able to predict the emergence of the LaGrande Technology (see question 15 in the above FAQ).
So we should expect a certain amount of controversy and people lobbying to resist the acceptance of this patch.
