(2) Hold up a bit updating your source trees...

    Putting this in your /boot/loader.conf:

    kern.mmxopt=0

    Will turn off the FP copy code which is causing the X server problems
    (and probably other problems as well).  

    I should be able to fix the problem today, since I can reproduce it so
    easily!
