You need Solaris 2.8, which has lofi

basic idea:

lofiadm -a /path/to/iso
# will return a device (something like /dev/lofi/number)
mount -F hsfs -o ro /dev/lofi/number

See the man page for lofiadm on 2.8 for all details, and note that the
example ISO they mount this way is a Red Hat Sparc ISO ;-)
