I've made a similar post over at the other thread but I'll state it here as well for simplicity sake. This "fix" works; it allows for more than 4GB of RAM... however, on my system with an nForce4 MCP61 chipset with a SATA DVD-RW. The DVD-RW does not respond anymore... until I replace the kext with the old one and go back to less than 4GB RAM. Since there are no IDE ports on my board so this "fix" is only good for systems like mine with external DVD drives.

Hope this helps.
