The short answer is the FAQ is probably wrong. Well, not wrong, just
sort of outdated.
You don't really need to worry about kernel size since someone figured
out how to get a bootloader into the linux /boot/vmlinux.gz area. That
thing knows how to find wd0a:netbsd just fine, and it has no firmware
limitations. If you used the 1.6.1 install or recovery CD (whatever we
are calling it now), then the vmlinux.gz file that came with it is a
bootloader. YOu want this. That way you just put any kernel you want
into your netbsd root on wd0a and go crazy.
If you need this bootloader, let me know. I can probably attach it.
