/usr/ports/UPDATING

20090124:
AFFECTS: users of x11-servers/xorg-server, sysutils/hal
AUTHOR: rnoland@FreeBSD.org

sysutils/hal has been updated and should now properly detect
mice for use in Xorg. Use of AllowEmptyInput should no longer
be needed for most users and moused should now work fine.

今のportsの最新のhalを使うべし。
