I am currently using a trackball and I am not satisfied with the scroll wheel. I wonder if there is a key combination to enable "free roaming, scrolling" mode, which locks the mouse and scrolls the screen according to the mouse motion, just like two-finger scrolling in trackpads. So that I will map the extra key on the trackball with that combination and scroll around with the ball while pressing that button.

There is a workaround, and it is called Scroll Reverser. That screenshot says it all; you can invert scrolling per-axis and per-device.
USB Overdrive can do that but it's not free.
You could also add a rule like this to KeyRemap4MacBook's private.xml. The behavior when scrolling multiple ticks was a bit weird on the mouse I tested with; it only scrolled a full page about once every 0.5 seconds.
<?xml version="1.0"?>
<root>
<item>
<name>Test</name>
<appendix/>
<identifier>94D0530F-70BA-4DA9-BD45-C223A689A807</identifier>
<autogen>--ScrollWheelToKey-- ScrollWheel::UP, KeyCode::PAGEUP</autogen>
<autogen>--ScrollWheelToKey-- ScrollWheel::DOWN, KeyCode::PAGEDOWN</autogen>
</item>
</root>
You can also increase the scrolling speed with defaults write -g NSScrollWheelMultiplier -float 200.
