Hello, Been there, done that, for different devices - mostly PDAs.
First you *must* check the specs : optimism won't get you far if the pins have different fonctions (like they have been swapped) or require some minor adaptations. Get the reference sheets for each device, read them and understand them. If you still believe it should work, then comes the actual physical work of reballing, etc: normally you would use a BGA rework station, but that ain't cheap. However, you can do that with easy to find and unexpansive tools. There is a nice visual guide with pictures and explainations on : http://digit.que.ne.jp/visit/index.cgi?Linux%a5%b6%a5%a6%a5%eb%a5%b9%b3%ab%c8%af%a5%e1%a5%e2%2f%a5%cf%a1%bc%a5%c9%a5%a6%a5%a7%a5%a2%2fC700%a5%e1%a5%e2%a5%ea%c1%fd%c0%df You can use excite.co.jp if you need translations, but the pictures alone are quite evident. Train yourself with dead hardware from ebay - you make many mistakes the first time :-) Be sure to have a soldering iron with the thinnest tip you can find, stripping wire, and a hotglue gun. It will come handy should you damage the motherboard by accident (it can happen; cutting a track, etc). If you need more information/help, tell me. I'm not sure I can help you (it's been a while since my last serious hardware hack) but I'd be happy to point you to people who can.
