I have a 2 * R9 280X and a 7850 Card in the same rig.. So I've needed to use -g2 in the first 2 and -g1 in the last one.. Cgminer had a bug with this parameter that only allowed a global -g parameter (same for all cards)
So, I've modified vertminer to add the changes from a cgminer 3.7.2 fork. Here is the original diff

I've builded this in Centos 6.5 and works perfectly. So, this is my contribution.
