Comment (by taos):
Using r41256 (gcc2hybrid) with an old centrino notebook (Pentium M 1,3
GHz, 1280 MB RAM) with Synaptics Touchpad.
Top command in terminal shows a cpu usage of
* ca. 15 % for thread "Ps/2 Touchpad 1 watcher", while using 2-finger-
scrolling with touchpad (see "top_touchpad.txt").
* < 1 % for thread "USB Mouse 1 watcher", while using scroll wheel of usb
mouse (see "top_usb_mouse.txt").
For comparison, the output of top with r37573:
* < 1 % for 2-finger-scrolling with touchpad (see "top_touchpad_old.txt")
* < 1 % for scrolling with usb mouse (see "top_usb_mouse_old.txt")
