the correct worksize reported from the cards I have is 256 but they tune better on 128

also the correct vectors reported is 4 tuning in on 4 reduces mh/s by at least 30% for those cards

cgminer default (setting nothing) is vectors 2 and worksize 128

setting the worksize to 256 on my 5850 gets me 5 more MH/s and usually the card's thread freezes within minutes... means xserver stales means reboot (no kill -9)!
