DRM of Vista broken?

This was not unexpected, but this made my day: Alex Ionescu writes in his blog, that he is able to break the digital rights management of vista. He was able to deactivate driver signing and thus he can inject a driver that circumvents the copyright protection mechanisms. If this is true, this has two interesting implications:

• Strictly interpreted the keys for Vista to play HD content must be revoked and all new HD medias need a new key for windows. This is not exactly the stuff you want to hear promptly to the general availability of Vista ;)
• Driver signing was touted by Microsoft to be an protection against malware. This proctection didn´t even survived the GA day. Can you really trust Microsoft that they are able to build a secure OS?

I hope that his breach will be confirmed soon. They had five years to develop the next version of XP, and weren´t able to make it right. One question: Who were the NSA employees who helped Microsoft? The janitor and the till girl in the cafeteria? Sorry for the spitefulness, but i expected more from the allmighty National Security Agency.
