Well in the end the OS need to support it so this doesn't concern us.
In some new ARM cards there are something called TrustZone which can
also be used to implement DRM.
What Intel does is only offer the ability to implement DRM in the OS
through hardware support.
I don't defend them and say this is a good thing but a hardware
supplier can never force you to use a specific OS.
ARM TrustZone is not enough to have bullet proof DRM system, as it does
not offer trusted I/O (i.e. secure channel to audio and video).
Other than DRM TrustZone can be used to do some nice things to make
operating systems more secure; e.g., manage keys in a secure way (you
don't have the same problems as with Intel HT ;-))
