IMO if you wanna bridge your MAC connection to Backtrack you have to work it out in Fusion.... furthermore is the easiest way to bridge them.... Fusion creates a Virtual DHCP server and Backtrack will get all the needed Parameters from it as you activate etho....

Of course if BT is running as a guest VM, physical interfaces must be handled by VM software (in your case Fusion).
# First create a loopback if needed and not already set
iface lo inet loopback
# Then the bridge
iface br0 inet static
# Now the most important data (which interfaces in the bridge: in this case Wireless and Wired)
bridge_ports eth0 wlan0
