Same problem here, on an Asus laptop with Intel (945GM) graphics.  Still
fiddling with it, but I can restore proper operation by starting
X then (ctl+alt+fn) moving to a tty.  I start X by ssh'ing from
another machine.

I have another machine with intel (945G) graphics that does not have the
problem.  But it's not a laptop.  Next tests are to remove laptop
specific daemons from rc.conf to see if that helps (since both these
machines are almost identical in configuration).
