It SOUNDS (though I'm not sure) that he wants to know how to add his
own modules to the kernel.. (i.e. /sys/conf/files etc.)
(and possibly a user interface) (new syscall? ioctl on a device?)

add the files to /sys/conf/files, making them dependednt on an option
such as 'distos'   (lower case)
then in /sys/i386/conf,
make a config file by copying GENERIC to MYCONFIG,
and add the line 
options DISTOS		(upper case)
(and you should add teh DDB option as well if you are experimenting)

any changes you make in existing files should be bracketted by:
#ifdef DISTOS			(upper case)
#endif
then:
in /sys/i386/conf
type:
config  MYCONFIG
cd ../../compile/MYCONFIG
make depend 
make all
make install <-- if you're adventurous
