I believe it's cleaner and a bit faster, once you don't have to do a lot of
if's as you do into ioctl().

Every char or block device has a major and a minor number. The file
/dev/ is just a special file pointing to those major and
minor numbers in order to access some device driver from userland. You
can have a driver running withtou any dev file accessing it
...
But avoiding to compile some modules won't optimize your system as
well, only your compiling time.
