You don't say which version of NetBSD. I'm running slightly-post-1.2
NetBSD/sparc on a headless IPC and it works Just Fine. (Though
admittedly, I do have the eeprom set to point to ttya; I'm not relying
on it autoswitching because there's no keyboard.)
I haven't tried anything newer on a headless SPARC of any stripe, at
least not yet.

Again, news to me. I get login promts Just Fine, though they're on
/dev/console, not /dev/ttya (same hardware, different /dev entry).
