Creating a file in /proc is going to require a kernel module or a
patched kernel. Chapter four[1] of _Linux Device Drivers_[2] describes
how to create a file in /proc.

That said, it's no longer considered good form to add anything to /proc.
The new home for this information is the /sys filesystem or debugfs.
LWN has a quick guide for using debugfs[3].
