I am a NetBSD developer, I know exactly what it runs on. The 68k systems are all 32 bit, the supported PDAs can run Linux as well.
I'm sure you're a fantastic developer, but you're an absolutely terrible evangelist.
I do wonder if NetBSD/VAX actually boots on real hardware. The reason why these machines are/were supported for this long is because of how different they are (keeping your software portable is a good way of ensuring high quality/correctness); but they also suck power like mad, and do eventually just die.
