I think that you're not quite correct. I've been doing some playing around
on my TinyCore Linux box and it doesn't seem to be an issue
with readability, but rather an issue of writebility.
If the directory is world-writable then the .DirIcon isn't used, but the
world-write privilege on the .DirIcon doesn't matter.
On my machine, if I'm a non-privileged user and the Directory and .DirIcon
are both owned by root and universally readable; then everything is fine.
As soon as the directory is world-writable then the default icon is
displayed instead of the custom one. It doesn't matter if the .DirIcon file
is world-writable as long as the directory isn't.

Is this info helpful?

It seems to be some sort of security feature. The side effect is that you
can't have AppDir or use .DirIcon on a drive that has a format that doesn't
support file permissions. (e.g. NTFS )

Here is a link to the section in the ROX-Filer manual that contains
information for a possible workaround:
