What kind of processing do you want to turn off? On import Aperture may do four things: Face detection, generation of previews, scanning for places, raw processing (if you are importing raw). If you have added an Apple Script as import action, this will be performed to.
In the Aperture preferences > Import panel you can set Aperture to use camera generated previews, if available, and the general preview settings are in the Preview preferences panel.
Face detection can be disabled in the "general" tab of the preferences panel, and "Places" in the "Advanced" panel.
So, which processing do you want to disable, and why?

Aperture (and all Apple programs that render RAW data to an image) use the 'Camera RAW compatibility' function of OS X.
When you import your RAW data files into Aperture, the process simply copies the file into the Aperture library by default (or leaves in current location if you specify that option). Aperture simply renders the data into a viewable image file in the form of a JPEG preview. You can change some parameters in the RAW Fine Tuning brick in Aperture to change the render if you wish, but the Camera RAW compatibility function is designed by Apple to read that specific data from that camera in a specific way as determined by Apple engineers.
Note - Aperture does not actually alter the RAW file data on import or anytime after (other than one specific situation where you tell Aperture to write metadata to the Master - which is not a default setting). Your RAW data file is treated as 'Read-Only' by default.
Basically, you can't have Aperture show you a viewable image without the processing function of OS X.
Alternatively, you can use a Referenced library to allow other programs access to the RAW data and render in their own way (e.g., Adobe Camera RAW / Lightroom, Capture One or vendor proprietary software). This does come with some higher maintenance requirements on file management though.

RAW describes a family of proprietary sensor-data file formats. It is not an image format. You cannot see a RAW file. RAW files must be converted to image-format files in order to be displayed. That's what RAW Converters do.
If you don't apply any adjustments (either at import or after), the "Revert to Original" button at the bottom of the Adjustment tab of the Inspector should be grayed out. What adjustments have been applied? (They show at Bricks with a checked box.)
