Hi, I'm not very familiar with the cape manager, but you should get a look at http://www.embest-tech.com/community/index.php?topic=2845.0
I am using kernels 3.1x that do not have the cape manager, so I play with the dts files and rebuild a kernel each time. I told you about the BB-View because your LCD seems to be using 24bits. If you hookup your lcd the same way the BB-View is done, you should be able to get something. Can't help more than that.
