Thanks Louis
In the end, we got out the man-pages and converted to ifup:)

For the record, the bond inerface setup for 2 nics is:

 /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

iface eth0 inet manual
bond-master bond0

auto eth1
iface eth1 inet static
address 192.168.0.10
netmask 255.255.255.0

auto bond0
iface bond0 inet static
address 192.168.1.82
gateway 192.168.1.1
netmask 255.255.255.0
dns-nameserver 192.168.1.132
bond-slaves none

Cheers,
Steve
