Could you outline a specific case where it's done intentionally - and the

The term "overlapping" is a bit misleading.

To the driver author its overlapping, its overlapping on the physical address.

Guys please stop this crazy talk - when the same physical address is mapped to 
multiple virtual addresses is called 'aliasing' - the term 'overlapping' is used 
when memory ranges overlap ...
