I couldn't agree more with you Sam.
The problem here is that Intel is not (no longer?) doing its work to deliver rated-to-specs driver performance and support. I do not believe that the PowerVR graphics chip should be avoided like a plague if it weren't for companies (that's you INTEL) that license the graphics IP from ImgTec doing short of destroying the brand's reputation by non-delivery of support of the hardware's rated capabilities and published specifications.
I do believe that ImgTec should be putting pressure on its graphics IP licensees to deliver the goods as part of protecting the brand name. I even wrote something about it in one of ImgTec's blog: http://withimagination.imgtec.com/index.php/powervr/understanding-powervr-series5xt-powervrs-hardware-is-nothing-without-software-part-9#comment-966642962
Clearly, the problem is NOT in ImgTec, but is in INTEL that should have been doing the driver porting work, being the licensee of the proprietary technology. Sadly, now that INTEL realized their blunder, never are they to repeat again and now will be releasing next-gen Atoms with Intel HD graphics . Too bad they SHOULD have done this NOW with Atom Cedar Trails (Trials?). This is a great DISSERVICE to Intel's LOYAL customers, ESPECIALLY those who were LEAD TO BELIEVE that the underlying hardware is Intel but is only masquerading as something else, who BELIEVED that the INTEL brand meant GREAT SUPPORT.
