It should be relatively easy to reenable it, if it works. Question, since most people are happy with just running AQM on the wan link, why do you run it on 4 interfaces?

A) it is cool that someone is using this functionality and I am
curious as to what it was being used for... what devices did you use
it on, and why? (paste your config file?)

B) I think the problem is not the script but the ifb module getting
inserted with only two ifbs allowed.

try a:

/etc/init.d/aqm stop
rmmod ifb
insmod ifb numifbs=8
/etc/init.d/aqm start
