IBM on TCPA - Will it affect the Macintosh?

[MacCoaster]

IBM's Global Security Analysis Lab (GSAL) has done extensive analysis of the Trusted Computing Platform Alliance (TCPA) chip available on some IBM systems. We have the chip running under Linux, and have studied it extensively. In order to clarify a lot of misunderstanding about the chip, we are making available some helpful white papers and open source device drivers for Linux, so that interested people can test and use the chip in an open environment.

Does this mean a TCPA future for the Macintosh?

From the document:
My personal opinion (not speaking for IBM) is that DRM is stupid, because it can never be effective[6,7], and it takes away existing rights of the consumer. But this is not the place for that debate. To condemn TCPA for the ability to run a bad application is absurd. This argument is exactly like the arguments of governments in their attempts to ban encryption, under the rationale that encryption can be used by terrorists to hide their messages.
Interesting. This isn't the TCPA that I'm familiar with. Does anyone know if there are two separate TCPA platforms, one IBM/et al. and Intel/et al.? I ask because the latter seems to advocate DRM.
