You can setup a DHCP/BootP Server in your LAN, which will provide the  
Jornada with an IP and the path to the root FS. That's the way I installed  
NetBSD on my CF card BTW: I didn't have a BSD-compatible CF-reader, so I  
booted from NFS and did all the partitioning and installation on the  
Jornada itself. I'm afraid I didn't write any docs, but the diskless  
NetBSD HOWTO will cover pretty much everything you need to know:
http://www.netbsd.org/Documentation/network/netboot
Especially check out the sections "Setting up the dhcpd server" and  
"Setting up the NFS server".
