Modern Touchpads have lots of additional functionality including emulating
scroll wheels, moving objects (tapping), multiple mouse
button emulation, etc.
The driver I use is http://web.telia.com/~u89404340/touchpad/ 
Wikipedia has a good introductory article about touchpads:

Nice articel, but very outdated. The last change was in January 2001.
Almost all apps support at least vertical scroll events today and
there are new drivers, like the touchpad driver I use or the new evdev
(event device, see e.g.
http://www.linux-gamers.net/modules/wfsection/article.php?articleid=46)

What seems to be missing in X or freedesktop is:
- a common way to define the scroll offset across different toolkits
- a way to tell the applications which (virtual) mouse buttons are scroll
events (see https://bugzilla.mozilla.org/show_bug.cgi?id=231718)
