They only work in the SVN version (and future releases of AC), they are not in 1104 or versions prior to.
@ Lantry: There is a new variable "slowmove" in the SVN version which, when is set to 0, editmode fly speed is the same as the spectate mode fly speed, when it's set to 1, it uses the old editmode fly speed. Theres also a helper alias in scripts.cfg called "slowtoggle" which can be keybound to easily toggle between the two while editing. Sure it's not as customizable as your request, but it's a step in the right direction. :)
Btw, slowmove defaults to 0, and slowtoggle is keybound to mouse2 (right mouse click) if editing and if not using the "old editbinds" (/old_editbinds = 0) - the editing menu was moved to mouse3 (scroll wheel click) for this as well.
Edit: nvm, we've got a proper flyspeed variable now. :)
