IMHO acceleration is the only way for mouse drivers to properly scale from
low to high resolutions and has always been a built-in feature of mouse
drivers.
I've just checked that my old (1994) DOS mouse driver is accelerated: in
1024x768 the distance I need to slowly move the mouse by in order to make
the cursor go across the entire screen is roughly double of that I need if
I move it quickly.

But non portable because on every platform except Windows (even DOS !) the
Allegro mouse driver works on top of a low-level driver that has some sort
of acceleration.
That's why the Windows port was the only one to be affected by the 'mouse
moves too slow' bug.
