Because it is not a module. That code is always compiled in the kernel - TCP
uses it. Just use it.

To get your numbers more random you might wish to feed more noise into
"enthropy pool" - use every hard disk and network interrupt to add the noise
- look (grep kernel source) for places where

 *      void add_interrupt_randomness(int irq);
 *      void add_blkdev_randomness(int irq);

are used and see how to activate it.
