X fails after upgrade to 1.9

[Huub]

You mean the cursor moves when X is not running, at the console?
If so, you are running the mouse daemon and that is what is using
psm0.  moused then passes the mouse input to /dev/sysmouse which
is what X should use instead of psm0.  You can also disable moused
if you don't want the console mouse.  Look in /etc/defaults/rc.conf
for the settings.
Thank you. Disabled moused and working now.
