Which is a little bit problematic because nobody seems to really care about glamor - it doesn't seem to work on X.org 1.13 yet (more than 2,5 month after release). Which is sad because to use PRIME you seem to need the offload sink's X driver to be accelerated.The 2D support for the HD 7000 series on Linux is now being piped over the GLAMOR library to use 3D
Only partly correct. Not for hybrid graphics with "AMD Enduro".and while there is AMD Catalyst Linux driver support
vdpau has at least two components: Decoding and presentation. You can use vdpau from mesa for "presentation" (= rendering the decoded video on screen with scaling etc.) for every video format. But it will still be decoded mainly on the CPU for unsupported formats like h.264. Use vdpauinfo to see what formats are supported for decoding (and maybe you still need to set VDPAU_DRIVER=r600).
FWIW, radeonsi can handle much more than 'some basic 3D demos' now. It runs many real games / apps fine. 3D apps run at full acceleration including page flipping. We're very close to enabling full glamor 2D acceleration as well.
Obviously it's not nearly as mature as r600g yet, but it's certainly ready for wider testing by early adopters.
It is of course a sad thing that the fglrx puts HD4/3/2xxx series already to legacy and that the free stack still is far from being feature complete on the newest GPU arch. I'm quite fine with my HD5xxx (R800/Evergreen) and the free driver stack. But currently there are few things to make the Linux user completely happy on the GPU market. :/
edit: It's always a good idea to check the feature matrix on GPUs.

probably something for matrox exists as well
