As I understand it, the current scrypt maintainer has  his own mining hardware, so probably isn't interested in supporting competitors.
So you'd need to find someone willing to write and maintain a new driver for it, and probably Innosilicon would need to provide at least specs of some sort (and ideally sample hardware).

nwoolls (who used to maintain BFGMiner's scrypt drivers) has been MIA for a year or so, but maybe if you PM him on the  forum, he might get an email and be interested?
