X Stat to Y Bonus

my 5 cents
montebank is actually mountebank in complete scoundrel. It's wrong in all incarnations of this list.

I think these haven't been mentioned:
Bloodstorm blade 2- str to attack with thrown weapons, 1,5*str to damage with 2 handed throws
Dread Tyranny feat (races of destiny 154) - strength intimidate skill
trapkiller barbarian 3 (dungeonscape 8) - attack roll (strength) to disarm mechanical traps

Cha to saves + skill checks,  Channel Positive Energy: Fate's mercy(Kingdoms of Kalamar Player's Guide); morale bonus, requires turn attempt, lasts 10 minutes.

Depending upon how you read the errata, it either grants the bonus to all allies within 20 feet, or grants it to as many allies as you can succeed upon a turning check for.  Either way, it's still quite good.  Bare minimum, you have an excellent personal buff.

feat to be placed under the Int heading

[spoiler]Academic Priest:
Your path to faith is more scholarly than those of other clerics.

Prerequisite: Intelligence 13+

Benefit: For the purpose of determining bonus divine spells per day and maximum divine spell level, your primary spellcasting ability is Intelligence. If you have more than one divine spellcasting class, the bonus applies to only one of those classes. Your spell save DCs are not affected by this change.

Special: You may only take this feat as a 1st-level character. If you take this feat more than once it applies to a different divine spellcasting class each time. You may take this feat even if you have no divine spellcasting classes yet.[/spoiler]

from Legends of the Twins (Dragonlance campaign setting companion book)

All the dragonlance books other than the campaign setting are third party.
