It's running on a headless self-assembled PC. The original OS install
was Debian Sarge, upgraded to Etch.

They're all there, I just needed the right command to show them. 

maudite$ ls -l /dev/fd/
total 4
lrwx------ 1 martin users 64 2007-05-25 14:43 0 -> /dev/pts/2
lrwx------ 1 martin users 64 2007-05-25 14:43 1 -> /dev/pts/2
lrwx------ 1 martin users 64 2007-05-25 14:43 2 -> /dev/pts/2
lr-x------ 1 martin users 64 2007-05-25 14:43 3 -> /proc/23186/fd

I notice that they all owned by user 'martin' not the slimserver user
(which is user 'slim'). I also notice that '3' is not writeable. I
don't know enough about the secrets of /dev and /proc to feel confident
poking around in there. I did feel brave enough to try the following:

maudite$ chmod o+w /dev/fd/3
chmod: cannot access `/dev/fd/3': No such file or directory
maudite$ ls /dev/fd/3
ls: /dev/fd/3: No such file or directory
maudite$ ls /dev/fd/2
/dev/fd/2

I find this interesting but don't know what to conclude as I'm
definitely in my ignorance zone. Any thoughts on what I should do next?
