Okay, after boot it does default to the 60.5 rate, but only displaying the
black screen:
$DISPLAY=:0 xrandr                                   
Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 4096 x 4096

After switching to a different resolution or to the 60.0 rate (still a black
screen), I can't switch back to the 60.5 rate:
$ DISPLAY=:0 xrandr -s 1400x1050 --rate 60.5     
$ DISPLAY=:0 xrandr 
Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 4096 x 4096
