Err, Animal Companion certainly fits -- your companion is your mount!
Swift tracker could work -- interpret it as allowing you to track from a moving horse.
Woodland stride -- well, if you can share special abilities with your companion, it could be really handy for a mounted ranger in a forest. OTOH, it's not so great in general -- perhaps it could be swapped for some kind of ability more useful to a mount -- increased speed, endurance, carrying capacity, etc.
Hide in plain sight -- again, if you can share abilities, hey, you'll be the only guy that'll be mounted after hiding from the army of high-level orcs.Otherwise, this could be swapped, too. Or, heck, quit taking levels of ranger before you get HiPS; go fighter or barbarian or some prestige class.
Some customization for a mounted ranger would be cool, but perhaps not absolutely necessary; it would be fairly easy to do, I think.
Probably easier than recreating the "urban ranger" variant . . .
Look, by this stage with all these "revised" abilities to work with the horse as well, you are describing something that is not the ranger of 3.5E (or any edition, in fact).
Not only that, but you are treading on the toes of the paladin.
At this point, I also begin to wonder about balance: is the mounted combat feat path better than the archery or twf paths... and my instinct is "yes, it is".
As a result, the mounted ranger/scout would be far better implemented as a separate class, rather than trying to shoehorn the existing class into fitting it.
Cheers!
