This is a copy-paste from my production, Debian Squeeze. Just works:

auto bond0
iface bond0 inet manual
  slaves eth2 eth3 eth4 eth5
  bond-mode 802.3ad
  bond-miimon 100
  bond-updelay 100
  bond-downdelay 200

auto xenbr16
iface xenbr16 inet manual
#  bridge_ports eth0.16
  bridge_ports bond0.16
  bridge_stp off
  bridge_maxwait 0
  bridge_fd 5


If the mode is set to "static", ifupdown scripts get scared because of 
lack of IP address and netmask definitions.
As I understand it, the bond is actually assembled due to "slaves" 
keyword and the change to "UP" state is done implicitly somewhere else.
Walter, note that in your case, you better use "static" in the bridge 
definition, because you do want to specify address and netmask. Those 
parameters are not needed in your bond definition.
Also, it would be nice to know what error do you get when trying to 
bring up the interfaces. Comment out "auto" keyword and bring them up 
manually first, in the correct order. Watch for errors, they shall tell 
you what is wrong. Once it's working, enable auto back.
