Let me be the first to say - you sir, ROCK.
Cheers, n.
edit:
Could be neat to get a little collection of games together that would make sense to be played on a Kindle (slow paced, ... maybe text focused...) --
Detective Conan - The Mechanical Temple Murder Case
http://www.romhacking.net/translations/2151/
(works fine - part of the gameplay has screen scrolling)
Shadowgate

other potential candidates:
The Fish Files
Scooby Doo! Classic Creep Capers
Mario's Picross
edit: Those three are partly untested. I'll test them asap - would make more sense to actually post games that someone has tested already and that are working.+
edit2: In addition to being slow paced, games also shouldn't rely on full screen scrolling too much - because with the low refresh rate of eInk - if the entire screen starts scrolling, you wn't be able to make out much of whats going on. Fixed backgrounds and a few moving sprites are preferable.

edit3: Setting frameskip to around 30 makes scrolling backgrounds a little more legible. At the expense of frames of animation of course.
