Well it works but I'm not sure about stability. My old build from the 6th of November (r5276-09f90b7) was running perfect for 10+ days. I did a new build after a dirclean (r5388-6fcf422) and after sysupgrading my router was rebooting every ~5 min (just as my previous story before I messed up everything).
I then did a factory reset and then it became stable (wierd...!). I did setup everything manually as it was before (of course there are probably minor changes) and I have experienced two reboots within the last 24 hours. Of course you might not experience the same as me as it could be a combination of packages installed and how everything is configured but at least my experience is that the new builds are not as stable as the "old" builds.
