Until we get the Bestiary which comes out next month or so I can't really answer your question fully. I know in the Bonus Bestiary they had the rules for the Dragonnes as mounts and how the Leadership feat works in that case, but don't know about any others.
Dragonnes as Mounts
A character with the Leadership feat can take a dragonne as a mount using the animal companion rules. Such characters must have an effective druid level of 10th. A character with a dragonne mount counts as 4 levels lower when determining the abilities and statistics of the dragonne (meaning that the character’s effective druid level is 6th for determining abilities when the dragonne is first acquired). Taking a dragonne in this way counts as the character’s cohort.
