I've tried some small OpenCL improvements that got my card from 255 khash to 262khash. While it's a minor improvement I think it could be quite significant for GPU farms (2.6% = 26 cards working for free in a 1000 GPU farm).
Now, to the chase, this is the modified scrypt130511.cl (which you must use to replace the scrypt130511.cl or other similar scryptxxxxx.cl of the cgminer 3.7.2 source directory)

...you "make clean", "make", remove old .bin files from your cgminer dir (rm *.bin) and run cgminer again to create new .bins.
Check your current speed and intensity to see where you are at right now and then please report back with results of the new kernel. I'm curious what it does for 6xxx / 7xxx and R9's which have a different architecture than series 5xxx.
