The Older son of So6P had the eyes of him, younger one the body. What if the the descendants of these two sons divided into three separate clans:
Descendants of the older one:
-Uchiha
-Hyuga
-??
Descendents of the younger one:
-Senju
-Uzumaki
-??
The descendants of the older one have the "eyes of the sage" (Sharingan, Byakugan and possibly Rinnegan), whereas the descendants of the younger son have the "body of the sage" - The Sage Mode.
It was stated by Kabuto that there are three different versions of Sage Mode. And I'm assuming that everyone has a special requirement - a specific clan:
The toads for the Uzumaki,
the snails for the Senju
and the snakes for Kabuto's clan.
If you are not from these clans, you cannot use these Modes.
However, Jiraiya could use the toad-version of Sage Mode. Maybe he is an Uzumaki. OR it's vice versa. He is NOT an Uzumaki and therefore, he cannot use the perfect, bur an imperfect version of SM, whereas Naruto - an Uzumaki - can use a perfect one.
Orochimaru couldn't use Sage Mode and that would be the reason why: His body cannot perform it, as he is not from one of the above mentioned clans. But Kabuto can use the SM and this might be the reason why Oro was interested in Kabuto that much.
