Looking for a particular Laptop

Well, I've decided that instead of building a new powerhouse desktop to replace my ancient one, I would get a laptop, and a monitor. I want this because I wind up doing a fair amount of travel for work, and this last trip (a week in middle of nowhere) was pretty unbearable. What I wanted to get was the Dell 2407 monitor (24" which will also act as my TV), an nice speaker system wireless keyboard/mouse for when I'm home and have the laptop hooked up to a base station.

Here's the problem: I want a small, easily portable laptop, i.e. sub-15 inches. The other problem with this sub 15" is that I haven't seen any with a good enough video card to play any modern games at the native resolution of the 2407. I'm not looking for 100 FPS on Crysis or Oblivion, but I'd like to see 30 on new games, maybe even 50 on HL2.

If anyone can point in the right direction, I'd appreciate it.
