That sounds like a good idea. At least for the mice that we didn't 
recognize, that otherwise get basically "random" commands.

How about something like this:

 - if "mouse_noext" is set (which implies that we won't be doing any 
   probing), we also don't set rate/precision unless the user asked us.

   Thus "psmouse_noext" becomes the "ultra-safe" setting. We still want to 
   have some way to set things like wheel etc info by hand later on (ie as
   a response to the user _telling_ us what mouse it is), but that's a
   more long-range plan.

 - if we do probing, we first ask the mouse for its current details, and 
   we restore the thing by default afterwards. That at least should give 
   us 2.4.x behaviour unless the mouse is broken (and for broken mice 
   you'd just have to have "mouse_noext").

   Again, long-term we'd want to have the possibility of tweaking the 
   results later even with the autodetection.

Does that sound like a reasonable plan?
