I wouldn't be so sure about "it can't kill anything"... I got a working install of 10.6 on my Aspire E380. Audio was not working - so I installed the ALC888 package from the IPC 10.5.6 disc (which DID work for me with 10.5.6/8) - Now it won't boot (safe mode worked, but I wasn't sure exactly what installed, so I couldn't delete it). You never know what kind of dependencies or changes may be made in the background by installing something. Sure, a kext is ok, that can be fixed by a simple "rm -rf" command in single user mode, but be careful doing anything more than that - you CAN kill your system.

So, with that in mind, anyone know how you get the ALC888 chip on my MCP61/nForce 430 working in Snow Leopard ?
