Lore Mystery question

Focused Trance (Ex): You can enter a deep meditation, blocking out visual and auditory stimuli and allowing you to concentrate on a single problem, philosophical issue, or memory. This trance lasts 1d6 rounds, during which time you can only take move actions. During this period, you gain a bonus equal to your level on all saves against sonic effects and gaze attacks. When you come out of your trance, you may make a single Intelligence-based skill check with a +20 circumstance bonus. You may enter your focused trance a number of times per day equal to your Charisma modifier.

Lore Keeper (Ex): Instead of encyclopedic knowledge, you learn most of your information through tales, songs, and poems. You may use your Charisma modifier instead of your Intelligence modifier on all Knowledge checks.

Do these two Revelations work together, or does Lore Keeper change Knowledge checks to no longer be considered Int-Based?

Knowledges are still an intelligence based skill check, even though you are substituting your charisma modifier in place of intelligence for it.

I would say no. Knowledges are still intelligence based. Lore Keeper allows you to substtute you charisma mod for your intelligence mod, but you are not required to change it. If you used Focused Trance in a game I was running my rule would be the +20 bonus would apply to the check with your Intelligence mod and not your Charisma mod. Note that tales, songs and poems are all auditory and you are blocking those out in Focused Trance.
