Jornada 680 asks for "root device"

[Michael Wileman <jwileman%panix.com@localhost>]

I'm trying to install hpcsh on my Jornada 680e. This is the Dutch 
Railway version available cheaply right now. It has a qwerty keyboard 
with accented characters superimposed on the keys, accessible using 
the alt-gr key.

I followed the instructions i Valeriy Ushakov's "NetBSD and handheld 
platforms" document, and creaded a FAT and an FFS partition on a 512MB 
CF card using an i386 laptop booted using a NetBSD live CD. Everything 
seemed to work fine. I extracted the kernel tarfile into the FAT 
partition, and the rest of the binary sets into the FFS partition.

When I boot using hpcboot, the booting process starts, until I get

wskbd2 at hpckbd0: console keyboard, using wsdisplay0
boot device: <unknown>
root device:

It doesn't seem to find my wd0a root setup. If I try typing in wd0a OR 
wd0 or wd1a or anything else, it just responds with

use one of: ddb halt reboot
root device:

I had assumed the kernel binary would automatically look for wd0. Can 
someone tell me what I'm doing wrong? Do I have to recompile the 
kernel to recognize my CF card. Did anyone else here have this problem 
trying to install 2.0 on a Jornada?

Thanks,
Mike
