This is really great news!

Pardon my newbieness, but I have a few questions to ask:

1. Do you have to use a custom firmware to boot the NetBSD kernel?
2. Do you have a kernel config script that would be useful?
3. I *think* you are booting a NetBSD kernel from the linux /boot
directory. Is it possible to do like the mips based one and put a
bootloader there than can then find the NetBSD root disk with the
kernel in /?
4. Is there anything special that needs to be done from NetBSD to
create the ext2 partition? See this mail for what has to be done to
get it working on cobalt:
http://mail-index.netbsd.org/port-cobalt/2000/10/05/0000.html
(Basically what I'm asking is for anything special needed to be done
to the disk to configure it outside of the Cobalt box on some other
NetBSD machine.)

I hope I'm not bothering you too much. This is very cool news, because
the mips one, while cool, is not very useable for doing more than 1 or
2 things at once.

Thanks for your work!
