[RFC] hw/misc/macio/cuda.c: erratic mouse fix

Commit Message

For everyone who is having a problem with the mouse pointer acting erratically, this patch should offer some relief. By decreasing the polling rate of the ADB mouse, the mouse pointer becomes more manageable. I was always able to reproduce the erratic mouse issue by playing an mp3 in QuickTime Player on a Mac OS 9.2 guest. With this patch the problem was almost unnoticeable. 

Please let me know how well this works for you.

Note: I only have test this patch on a Mac OS X host running a Mac OS 9.2 guest. Hopefully it will fix the problem on Windows and Linux as well.
