the kernel is way too different in diablo as is the xserver-xomap too.
using chinook kernel will not help, you will not get past the flash screen.

I am currently in summer vacation, so development is pretty much in halt.

If you want rotation now, use chinook, if you want diablo, be patient. All good things etc.

I have asked an iNDT manager, that I know in person , to bundle the kernel and server as installable package. Let's see if they want to do it now that diablo is out.
