One level of changeling rogue with the substitution level from Races of Eberron replaces trap sense with:
1) Gather Info in 1d4+1x10 minutes instead of 1d4+1 hours
2) Sense Motive as a full-round action instead of one minute
3) Take 10 anytime on Bluff, Diplomacy, Gather Info, Intimidate, and Sense Motive
Oh yeah, you also get 10+Int skill points and one Knowledge skill of your choice as a rogue class skill.

ps - I'm having a total blast with my changeling rogue. There's some other neat stuff at 3rd and 8th levels, but the first one is just killer.
