[Q] Flashing Rom & Kernel of different version of M8? topic

Hi, thanks for reading.
I am a HongKonger. As I know, the global version of M8 is using the snapdragon801AB while Asia version is using the snapdragon801AC. I know the only different of the two cpu is simply overclocking to different frequency. Would the different make development very difficult to support the two at the same time? Or it will just be the same?
I afraid there will be less support for the Asia M8. Will this happen?
I am so sorry that my English is not good enough. Hope you guys could understand what I'm talking about.
Thanks.
