Hi Alexandre,
as far as i understood the kernel people you should go this way
(untested just written down):
auto bond0
iface bond0 inet manual
slaves eth0 eth1
bond_miimon 100
bond_mode active-backup
pre-up ifup eth0 eth1
post-down ifdown eth0 eth1
auto vmbr1
iface vmbr1 inet manual
bridge_ports bond0
bridge_stp off
bridge_fd 0
auto vmbr1.94
iface vmbr1.94 inet manual
vlan-raw-device vmbr1
auto vmbr1v94
iface vmbr1v94 inet manual
bridge_ports vmbr1.94
bridge_stp off
bridge_fd 0
