The idea that even a 1M kernel is huge for embedded systems these days is, well, getting archaic. Companies like Micromint are still selling 8051-based microcontrollers with 64K RAM, sure--but they're not even running operating systems, generally, just dedicated applications. Even current generation Z80 chips like the eZ80F9x have a 16M linear address space. When you're talking about even moderately complex applications, NetBSD's requirements for a kernel aren't outrageous.
