What does ISO9660 and 4gb file size have to do with each other.
Iso9660 is a filesystem type.  The iso image will be a file on the
standard linux filesystem, and its maximum file size is not related to
iso9660 standards in amy way. 

I have not tried mkisofs for some time so it may well have a limitation
on filesize it can create, but that would be related to the application
and not to the iso9660 limitations.  I burn data DVDs regularly from
image with more than 4gb of data and never a problem.

Ummmm... come to think of it I do use mkisofs ....  I use mondorescue
for my backups... that uses mkisofs to create the images for the DVDs
