Since you ask for ideas instead of answers ;)

On my system modprobe ifb has a configuration parameter setting number 
of interfaces, maybe this is playing into the equation on your system?

ip link show should reveal existing ifb interfaces, so maybe you can use 
that to find what is wrong with ifb0?

fwiw, find /dev/ -name *ifb* returns nothing on my system, however I do 
have /proc/sys/net/ipv4/conf/ifb0
