I have only tested it for GMA 915, it works amazingly without the paperclip hack, even though there’s mouse tearing occasionally, it should be working for GMA 900 too but I’m not sure, so try it at your own risk.
just replace the kext files with the ones from GMA950.zip and also replace the OpenGL.framework.
If you don’t know where the destination directories are, GMA950 kext files should be put into /System/Library/Extensions and OpenGL.framework should be put into /System/Library/Frameworks, and don’t forget to backup the old files.
