you could run a seperate instance of BFGminer in the background on minera, as I did for my dual mining on page 66 ish of Minera thread, you put the startup command into the rc.local settings on the dashboard settings page.

Essentially it would be

screen -dmS bfgminer /var/www/minera/minera-bin/bfgminer -o -u -p -S antminer:all --set-device antminer:clock=x0781 --api-listen --api-port 4030 --api-allow W:192.168.0.0/24

That will start bfgminer seperately behind the minera dashboard, with an antminer U1 at 1.8GHs, with the api set on port 4030 (so as not to interfere with the CPUMiner running on Minera) and allowing full control of the api from the 192.168.0.* network.

Obviously change the -S antminer:all --set-device antminer:clock=x0781 for settings that work for your device.
