Well I have managed to get a trivial example configuration up and running. 
It uses the Fedora initscripts to initialise the networking (c.f. using 
network-bridge script). It still uses the vif-bridge script for domU's. It 
might be of some use to others running FC4.
The setup is two GbE ports (eth0 and eth1) bonded together using 802.3ad. 
Over that I have setup a single 802.1q VLAN (id 10) - with the intention of 
expanding this to one VLAN per domU. I configured a bridge (br0). I have 
created a config file to add vif0.0 to the bridge. Lastly I have provided a 
configuration file for veth0 which provides a MAC address and an IP address 
for dom0.
I notice that the dom0 vif interface uses zero based indexes (i.e vif0.0), 
however the domU network interface numbers are one based (i.e. 
vif<domain#>.1). Is there a reason for this?
I'd appreciate any feedback, especially if I'm doing bad things.

Greg.
