I think I have an idea for a quite easy fix. Add to the MAKEDEV package an 
initscript that checks the kernel version and makes /dev/mouse point to the 
correct location.
In pseudo-code:

if kernel_version <= 2.2.17
  ln -sf /dev/usbmouse /dev/mouse
else
  ln -sf /dev/input/mice /dev/mouse
fi

I don't know if the policy would have anything against it... Comments ?
