This patchset cleans up a little bit the Apple CUDA emulation:
- correctly reject unknown commands
- correctly reject commands with wrong parameters
- support changing the frequency of auto-polling
- support changing device list probed in auto-poll
- remove unused commands (GET/SET_6805_ADDR)
- remove unimplemented GET_SET_IIC/COMBINED_FORMAT_IIC

GET_SET_IIC/COMBINED_FORMAT_IIC commands should be added again once
we implement the I2C bus provided by CUDA.

Neat! (I wish I'd seen this before trying to debug issues with this code!)
Do you have any plans to work on this code further? The VIA register code
doesn't seem to really match what the hardware does, and I've been wondering
if it's responsible for weird input problems under Mac OS, but didn't find
time to look into it yet (and don't want to duplicate effort).

I already have some code to add the I2C bus, but it's mostly used by MacOS 9 
which probably tries to configure some devices.

Do you have a Linux/NetBSD/... image, where I can run some command line tool to 
probe the I2C bus?
