Uh. I think Black and White actually benefits from touchpad, as it's easier to cast spells using a touchpad.
Neverwinter Nights is the best game on my laptop. It runs smoothly and doesn't require much speed. There is a pause in case you need to freeze. Same goes for KotOR - battles have active pause, are turn-based and you can avoid some of them.
Emulators are also very good. Just remap the controls, as most of the machines block on a bad configuration (you can't move your character, for example, if you use WSAD to move).
Every 2D platformer. Jazz Jackrabbit is awesome, so is its sequel.
Adventure games without fast actions. Sam and Max games for example, The Longest Journey, Syberia 1 and 2 (beautiful games, both graphically and story-wise).
Uh. What more? Fallouts, Duke Nukem Manhattan Project, Arcade America.
Quite a lot of games can be played on a laptop without the usage of a mouse.
