I'm really baffled by your statements above: what you're effectively 
saying is that if the person porting an OS to a particular platform 
is prepared wilfully to ignore the (well-understood and well-
documented) issues with that platform, they won't get their 
OS "certified" (by whom incidentally?). All I can say to that is "so, 
what?". If you choose to ignore information provided by hardware 
vendors, then tough. The fix is simple and efficient to implement: no 
need for kernel panics or system failures.

By the way, it's completely irrelevant who's to "blame" for this 
(Philips or ARM or whoever): the only relevant thing is that the 
issue is documented and a fix provided (which it is).

It seems to me you are more interested in pointing fingers of blame 
at people, rather than contributing anything positive. The issue is 
already well understood and documented. What exactly are you trying 
to achieve or add to this?
