In one of the Sage Advice columns in Dragon Magazine, somebody asked if the big guys would ever make canon Dragon Disciple totems outside the original ten Chromatics/Metallics. They responded that there were simply too many true dragons to give a good list of all of them.

Bull crap.

I've done a little digging and I found a website that covered a majority of the dragons I'm trying to totemize, but there's still several I'm trying to cover, which I've listed below along with what resource they appear in:

Sand Dragon (Sandstorm)
Incarnum Dragon (Magic of Incarnum)
Purple, Orange, and Yellow Dragons (Dragon Magazine Compenium Volume 1)
Hex Dragon and Tome Dragon (Dragon Magazine 349)
Sea Serpents (Dragon Magazine 345)
Ferrous Dragons (Dragon Magazine 356)
Planar Dragons (Dragon Magazines 321 and 344)
Dzalmus Dragon (Dragon 349)
Brainstealer Dragon (Dragon 337)
Spinewyrm (Dungeon Magazine 110)
Lung Dragons (Oriental Adventures)

I'm mainly looking for help coming up with their three extra class skills for said totem, and their spell-like/supernatural ability to complement their totem. Breath Weapon scaling is not an issue, as I've got a guide for that on the website.

((Edit: I actually finished the core dragon shaman abilities. The only things I need now are ideas in general.
