iMX53 enablement

Hi, I've been trying to get accelerated graphics up on imx53 - unfortunately, causing lots of crashes and little else.

I think the problem is that so far, the only version of the graphics driver that has been released is for Gingerbread, and it simply doesn't work with ICS. However, some of you have much more experience than me with making sense of binary blobs, so if someone has some spare time, feel free to look. ;) I've attached the script I'm using to push the binary driver into system.tar.bz2.

I've looked at their kernel sources and gralloc tree, and it looks like we have everything we need there - but of course I could be wrong.
