fix for : "scrolling works only after waking up from sleep"

I think i found a simple fix for the scrolling problems encountered with the releases 0.26 and 0.27.
For me release 0.25e was the last working release so i started to look at the changes made between 0.25e and 0.27. I tried to run the daemon from 0.27 with the driver from 0.25e. This combination worked and as a consequence the scrolling problem seems to be caused by a modification of the driver (AppleADBMouse.cpp) made after 0.25e.

After some ( trial-and-error ;) ) efforts i figured out the following:

In lines 406 - 407 (iScroll::start()) of AppleADBMouse.cpp some setProperty calls are commented out. If you re-enable the first two it seems to fix the weird scrolling problem.

// modified dub:
setProperty(kIOHIDPointerAccelerationTypeKey, kIOHIDTrackpadAccelerationType);
setProperty(kIOHIDScrollAccelerationTypeKey, kIOHIDTrackpadScrollAccelerationType);
// setProperty(kIOHIDScrollResolutionKey, kDefaultScrollFixedResolution, 32);
// end modifications

I choose not to include a patch file because the fix is just to un-comment two lines of code.

I really don't know why this fixes the issue for me...

It would be nice if you could check if this really fixes the problem.

regards,
Philipp
