Hi,
Just speculating here - since 200+ users have the same model, and it worked fine.
You said that keyboard did not work during installation.. right.. thats common - a usb keyboard can fix that.
Then, when you are done installing and you boot into OSX - did you install EDP (download it from the WIKI's EDP page, not to be confused with a bootpack)
.. and did you do a build afterwards ?
