Well I am using a bash script that runs a PostgreSQL query and then uses beanstool to put things into the beanstalk queue. All this is a cronjob, on a x86 server and nothing to do with the router itself.
I checked and I am on a 5 version of the OS. The only thing it really does is write to some /sys files so it is likely to still work… if not it would (likely) be a super easy 5 min job to hack the code to make it work.
