I don't consider the memory allocation that [new] and constructor/destructor operations perform to be "hidden". In fact, anyone who thinks that [new] doesn't allocate memory is a moron. [new] is nothing more than a malloc followed by an indirect function call with a single pointer parameter passed. There's nothing hidden or secret about that.
However, I do agree that for many kernel operations, C++ doesn't help any. However, that doesn't mean that people writing device drivers should be excluded from using C++. Having known C++ keywords in header files, and refusing to change them because you don't want other people using C++, is selfish and narrow-minded and not something that a Linux programmer should be proud of.
