The same steps apply to 3.40 OE, if you don't want to upgrade to 3.71 M33, which has a rather complex install routine. (You need to do this: 1.50 - 3.52 M33 - 3.52 M33-4 - 3.71 M33 - 3.71 M33-2, then install the 1.50 kernel addon. That's a lot of firmwares you need to go through to get the end result.)
