Okay tethering has almost definitely been purposely disabled in the Wifi driver. If I go to the Terminal and follow the manual instructions:
wifidriver -i
iwconfig eth0 mode Ad-Hoc essid PreNet
I get the following message:

Bluetooth tethering using My Tether is working properly though. (Turn on USB tethering, then connect to the Pre via Bluetooth PAN). I presume that should mean USB tethering itself works as well.
