Any driver C++ code would still need a C++ run-time. Either you must statically link it in, or you'll have a problem with multiple drivers using different C++ run-times. If you statically link in the run-time, then you're bloating the text of the kernel. If you're not then you have a problem. C++ is bad because of its ABI issues, really.
