There are quite a number of reasons why non-root users can't mount smbfs
shares right now; the first of which is kiconv, as you mentioned, but
there are also problems with the permissions on /dev/nsmb*, suser() checks
in netsmb, and the credentials mount_smbfs passes in to the kernel which
get subsequently rejected by netsmb:
        ctx->ct_ssn.ioc_owner = ctx->ct_sh.ioc_owner = 0; /* root */

The easiest way to get non-root mounts working is to enable the
#ifdef APPLE code in libsmb and mount_smbfs, then make mount_smbfs
suid root. Whether this is actually any less secure than adding
proper support for user mounts is debatable.
