SunOS CD-ROM's in the UFS format are *not* ISO-9660 compatible.  They are in a 
so-called UFS format, which is apparently their idea of a UNIX file system, 
but on a CD device (well, it could happen...).

As far as I know (but I could be wrong), there is no support for this 
filesystem type in FreeBSD to-date.
