That's not the point, 99% of the current ARM boards will not 'survive' either, 
10-20 years down the road.

I think you missed David's main point: life inevitably went on and few of the 
old x86 hardware 'survived' physically, but past hardware versions have not 
littered the kernel source with half a million lines of source code in the 
process ...

Having strong, effective platform abstractions inside the kernel really helps 
even if the hardware space itself is inevitably fragmented: both powerpc and 
x86 has shown that. Until you realize and appreciate that you really have not 
understood the problem i think.

Thanks,
