Depends on the distribution. Sometimes it's enough to add:

blacklist thermal

to /etc/modprobe.d/*.conf, but sometimes init scripts actively load the
thermal driver, so you have to hack them or at least edit
distro-specific config files.

Yes. The thermal driver will access the same I/O ports as the w83627ehf
driver, without any synchronization between them, so very bad things
can happen.
