I think the point of the AMD Fusion rumor @ Apple, is only wrt. pricing and probably an incentive to get Intel lower its prices. IIRC, Intel chips for Apple products are custom designs (specific additions or removals), so this costed them (Apple) money, I'd think. If you look at the G45 VA-API driver, you can notice that there is specific shader code for the IGP used by Apple.

It's the same as the completely open cpu, can't recall the name to it, it's also on the 486 level.

In addition, Intel reportedly plans to support OpenCL on Sandy Bridge, in a roundabout way. Apple has embraced OpenCL by integrating support in to Mac OS X 10.6, and using NVIDIA controllers in its lower-end systems meant that all of Apple's shipping computers were compatible with the standard. The basic architecture of Intel's Sandy Bridge IGP can't support OpenCL functions at all?it's based on an archaic, specialized design that doesn't do GPGPU and will be replaced in Ivy Bridge later in 2011. But, Intel has been working on supporting OpenCL on its CPUs?with four simultaneous threads available on dual-core chips, it may be possible to execute OpenCL code acceptably fast on the CPU itself.

Some info:
On the basis of the IDT Centaur acquisition,[2] VIA appears to have come into possession of at least three patents, which cover key aspects of processor technology used by Intel. On the basis of the negotiating leverage these patents offered, in 2003 VIA arrived at an agreement with Intel that allowed for a ten year patent cross license, enabling VIA to continue to design and manufacture x86 compatible CPUs. VIA was also granted a three year grace period in which it could continue to use Intel socket infrastructure.
