PR kern/8127 (was xsrc/8127) describes a problem with X11 window movement
on a heavy loaded system. While looking at the old PS/2 and at the wsmouse
driver I came to this conclusions:

1.) The old PS/2 driver keeps track of all mouse movements in internal
    variables and returns a single delta pair on an ioctl() call.

2.) The wsmouse driver reports each mouse movement as a single event in
    a queue.

The question is which behaviour is the correct one? IMHO it is 1) because
it avoids problems like the on described in PR 8127.
