You have two options, the way I see it: a distro (preferably iATKOS L2 or better) or a retail CD and Boot-132 or the like (less likely for things like wireless to work OTB, which means more time and energy.) I'd personally try iATKOS first, make sure to use "-v cpus=1 platform=ACPI" and the like to get the CD to boot. Look for a torrent, it usually has a lot of seeders (not sure if I'm allowed to link to it.) Do some research to see if your hardware is compatible (namely the Core i3; also I know for a fact that your Wi-Fi doesn't have a driver OTB, so you'll need to find one. They're called "kexts", by the way, for "kernel extension.)

Last of all, do some research on how OS X works, and about DSDT (which I don't know enough about to help you too much, but you apparently need to patch it for whatever reason.)
