I'm positive. The actual listing of /cdrom is:

If I mount it from other FreeBSD or Tru64 host, it's also seen properly. I guess
it's just Solaris problem. I tried Solaris 7,8,9, Tru64 5.0,5.1,5.1a and FreeBSD
4.7,4.8 and 5.0.

Now I guess it's Solaris specific. If you want some more details, let me know.
