I've got these.

Isn't this only necessary for an initrd?

I have CONFIG_BLK_DEV_RAM enabled. (I think this is the ramdisk
option you're referring to)

I didn't make anything a module, it's all built in or non-existant.
That way I don't need to deal with initrds or modules for anything.

No. The 'rdev' modification didn't help either. The exact error
messages I get on the client are :
~~~~~~~

The server is 192.168.1.1. It has portmap, nfsd, and mountd running.
It has ALL:ALL in /etc/hosts.allow. The path /tftpboot/kiosk0 exists
and contains a chrooted manual install of woody.
The server has no messages in it's log. I can mount that directory
via nfs from another workstation (that has a disk).
If I boot the potato installer on that workstation, I can ping the
server.
Thanks for your suggestions.
