All I did was buy a Mac-compatible Bluetooth dongle from Fry's for about $10. It plugs into USB and the Hackintosh sees it just fine. I'm using my iPad now, but if you want me to provide details, send me a PM and I'll post everything I can find out about it.
This ones a bit different tho, the dongles (apart from the old DLINK one with Mac firmware) can't wake from sleep using a bluetooth device, like if you have a Bluetooth keyboard or mouse and you press a key it wakes up, no USB keyboard/mouse needed :-D
I did the MacBook bluetooth module trick and it works great, my Wireless Keyboard, Magic Trackpad and Magic Mouse works flawlessly and I can wake from sleep with no delay. Also works fine in Windows with no need to repair them once you paid them in Windows.
On a downer it can't control the BIOS or bootloader :-(
