I've successfully built a kernel _on_ the DC but it doesn't fully boot.  
It doesn't get the ethernet configured.  I've haven't built too many
NetBSD kernels so I could be missing something obvious.  I've included my
config file below.

Could somebody who's built a bootable kernel post a config file?

Regards,
