I'd rather leave it out for now, and merge it when it has a chance to
work. Merging non-working code is confusing at best.

2.6.19 at best.

No, not everyone has this device. We don't have a default for other
hardware monitoring drivers.
This should depend on HWMON, and probably EXPERIMENTAL too, until it
gets some wider testing.
Also please respect the alphabetical order.

If you are going to have many source files and a composite module,
please create your own subdirectory under drivers/hwmon and put all
your stuff here. The kernel build system is notoriously bad at handling
multiple composite modules within the same subdirectory.
I won't have the time to review such a big and complex driver within
several weeks, so people who want this driver in 2.6.19 will have to
review it by themselves.
Thanks,
