>Description:
	The kernel global variable "tickadj" is set to a default value of 
	240000 / (60 * HZ);		/* can adjust 240ms in 60s */

	which is 40 us adjustment per tick.
	NTP works much better with a tickadj of 5 us adjustment per
	tick.

>How-To-Repeat:
	see xntp documentation; we shouldn't need to run tickadj to
	patch it on each boot..

>Fix:
	change /sys/conf/param.c::tickadj to be set equal to the
	constant "5".
