I managed to compile couple more things.
gtk-engines-thinice - My favourite GTK2 theme. Small widgets good for 640x480 screen. (Actually I use it on my 1920x1200 desktop as well)
htop - sexy process viewer/manager, replacement for top
lcms - little color management system
ufraw 0.7 (uses lcms). ufraw is raw conversion utility for images from digital cameras. I had to modify the main dialog layout to almost fit into 640x480 screen. It loads and converts images from my Pentax dSLR just fine. It takes A LONG TIME to convert the image, like couple minutes. This should be useful for previewing images on trips or so. Take SD card from the camera, put in Zaurus and play!
