Thanks, Koen.

This worked and was very easy to setup, and worked first time - 
something that I haven't experienced for about three weeks!

Here's the short HOWTO:

To rename network devices using udev.

The udev scripts reside here:
/etc/udev/rules.d/
and are actioned in lexical order.

So, create a script that will run first, say:
010_local.rules

Query the interface to find its (all lowercase) MAC with:
# udevinfo -a -p /sys/class/net/eth0/

Add lines for each interface like:
KERNEL="eth*", SYSFS{address}="00:52:8b:d5:04:48", NAME="lan"

After you add rules, they must be made known to udev by:
# udevstart

A reboot will be necessary for network cards, because the drivers need 
to be reloaded.
