Most of the C++ bloat comes from templates. C++ code without any templates is comparable in size and execution speed to C code. So as long as you don't use templates (which basically means avoid the entire standard C++ library) then C++ would be a fine language for kernel module development. Of course, ISO 9899-1999 fixed the two most annoying C problems -- declaring variables only at the start of a block and no // comments.
