The assumption that only you get this output is wrong, see:

$ cat /proc/devices | grep 14
 14 sound
 140 pts
 141 pts
 142 pts
 143 pts
  14 unnamed

And when I grep /dev for a block device with major 14, I don't get
any results. That's why I wrote:

: I think unnamed devices are not available through /dev and only
: used internally by the kernel.

Character devices with major 14 are all related to sound, mixers,
sequencers and so on.

In kernel documentation, for major 14 I see

    block   BIOS harddrive callback support {2.6}
    
but since this is a 2.4.20-19.9 kernel, I don't know whether it is
normal or due to something backported by Red Hat. And I haven't
started any investigation due to other things on the TODO list.
