Funny you should ask, I literally just ordered an a1260 display assembly yesterday for my a1226, it's on rush shipping so I'll update this post after I try it. I already replaced the top case (part that contains the keyboard and trackpad) for it with one from an a1260 which works flawlessly, I even got the multitouch features and new function buttons along with it, worked as soon as I installed it, no fiddling. These two models seem to share a lot of parts, so I'm crossing my fingers along with you.
BTW for anyone else reading, my a1226 took a spill down some stairs, the screen actually tore off of the laptop, IE the hinge is still attached but the lcd and back cover are completely gone, case bent up, ribbon cables spilling out of it, but I plug it into an external monitor and it hasn't missed a beat. I'm posting right now on half of a macbook pro haha. These old macbook pros are tanks!
So I installed it, and it's a little finicky. I saw a few other sources that say it should work, but mine only works once you connect and disconnect an external display, otherwise the display isn't detected. I may have damaged something when I installed it, but I'm still fooling with it. Search for the display assembly on here, there's some more info. If I figure out what is going on I'll let you know.
