May not produce the same feel, but there is:

  defaults write -g NSRepeatCountBinding -string "^u"

> This default controls the numeric argument binding. The default is for numeric arguments not to be supported. If you provide a binding for this default you enable the feature. This allows you to repeat a keyboard command a given number of times. For instance “Control-U 10 Control-F” means move forward ten characters.
