yes, for the generic kernel. No, once you build your own and define
where you want it to be possible. But for the install boot it should not matter.

Hm, the official document which should tell about is the INSTALL
document, and I think you're right, its not there. I'll fix it for
1.1pl2 and 1.2.

Yes. While the Emplant might be the culprit, if it misbehaves, NetBSD
doesnt touch it, and so it should in theory be quiet.

However, there was a bug where too much of Zorro III i/o space could not
be handled in the kernel and would give crashes, eventually. I don't
remember for sure when this was fixed; it might have been after the initial
1.1 release, but you could be happy with 1.1pl1. I'll check and tell
