Hardware Personality Profiles

Hi All,
I'm looking for a bit of advice concerning preparing Unity for new headset hardware. I would consider some attributes of the display hardware (like distortion correction) to be essentially embedded and not to bevisible to a Unity application developer. Equally, some aspects of tracking might also be hardware specific and would be of no concern to an application developer.
So, my question is: How is it possible to embed display hardware details into Unity such that it performs operations such as distortion correction without visibility to the application writer? Is there some kind of hardware layer that can be written or is there some form of hardware-specific personality module that can be plugged into Unity for this purpose?

Thanks for any pointers,
Dave
