I used a laptop HP Zv6132US, with an upgraded CPU being AMD single core 64 4000+, and with the Radeon Xpress 200 controller. I installed using the Kalyway 10.5.2. distro. It went according to the plan, I selected no video driver, mouse and keyboard worked fine. Did not need the external monitor "trick". But what worked for me might not work for you. The best I could do was use Callisto to set my screen resolution. I got 1280x800. The Katana driver would not work for me. Without Quartz Extreme/Core Image my video was a bit jerky in full screen. The BIOS was set to "Sideport" for video memory allocation. With full support for the Radeon card it would have been a great Hackintosh. The drivers you have may work if you edit the kexts to show the correct vendor and version numbers in the plist files, but not for the Radeon 200 as far as I can tell. I got my sound, wireless, and ethernet working using this method. The power management driver worked fine and showed battery charge etc. Time Machine worked. I never got the sleep function going, but never really tried. Just in case anyone is interested it rates 65.16 on Xbench with 1280mb of ram and a 5400 120gb HDD. Consider changing your graphic controller for one that Apple use. I am not an expert and someone else might have a better experience with your hardware.
