But it isn't in /usr/bin (assuming that this is the /usr/bin in the root directory).

I'd like to figure out a few more things:
1) What is the purpose of the above mentioned step 1? Is it truly necessary?
x11vnc is an VNC server. Assuming that you are trying to use your nokia as a client, you don't need it.

The purpose of x11vnc is to "capture" an existent X session in a linux box, and to "serve" the display through VNC protocol. In case of the n810, this means that you can see the screen of your Nokia, remotely, from any other computer, using a VNC client.

The purpose of adding -localhost option when launching x11vnc, is to disallow the access to your display from any external host. Only connections from localhost are allowed. This, apparently, goes against the objective of using VNC in first place, but it makes sense when you plan to use ssh tunnels. Remember that, when the tunnel is properly configured, the connection to the VNC server does occur from localhost (from the sshd process). [See my previous post]

It is not closely related. You can make an ssh sesion, with or without tunnels. If the session is with a tunnel like -L5901:localhost:5900, then the conection in the vnc server side is from localhost, so in this case you get an extra level of security by using the -localhost option, because this option will not prevent you to use the tunnel, but it wil prevent to any other trying to connect the vnc server without using the tunnel.

It is not installed by default. You need to install the x11vnc package.

If I am correct in my assumption in 4), I would like to be able to locate x11vnc within xterm so I can tweak it if need be.
You are correct in your assumption. However, now I'm not following you... So, finally you have found x11vnc for your nokia or not? And, is this what you were looking after, or it was the reverse scenario (vnc server in your windows an vnc client in your Nokia)? I'm a bit perplexed.
