The only way I can see you could acomplish this is to write a
interrrupt handler that's activated each time you access video
memory. This is a complex thing, and has two withdraws:
1.- Uses memory resources
2.- Slows down video memory access

In conclusion: The best choice is to
mouse_pointer(0)/mouse_pointer(1) each time you write to videoMem.
This is quite fast (just a INT call).
