Have you tried the updated
Printer Driver Ver.3.00 for Windows Vista x64
with the updated tool box
Tool Box Ver.188.8.131.52.mf08 for Windows 2000/XP/Vista (32bit)
I understand that one is 32bit and the other 64, but seems kinda unproductive to issue a 64 bit driver if the availabe tools don't work with it.
Also you can ask Canon directly via e-mail on their support page:
