On a -current system from today after applying the patches I get:

...

/home/sysbuild/src/sys/rump/dev/lib/libwscons/../../../../dev/wscons/wsmouse.c: 
In function 'wsmouse_precision_scroll':

Otherwise I'd be interested to test - my synaptics trackpad is very 
sensitive to touch, anything to get it better is welcome (I've tried a 
number of sysctl parameters, it is usable now, but I still prefer to 
attach a mouse when running NetBSD on it).
