In this tutorial i'll show you how to get working graphics ATI 5450 in Lion 10.7.3 hackintosh
i am assuming that you already installed boot-loader and other kexts if you dont you should install them first, for more on installation guides see http://www.tonymacx86.com and get back here when you install everything except graphics
NOTE : I do not issue any guarantee that this will work for you! use google for other troubleshooting
