Well, I think I understand a little bit this fear of merging new driver
that "obviously can't break anything" in arbitrary stage od development.
See below.

If you have a hardware that hasn't been supported by the previous kernel
versions at all, then everything is fine, just no driver is bound to the
device, and the device doesn't work. If then -rc9 comes with a shiny new
driver for this hardware, it gets autoloaded. If it is buggy, your system
crashes. This is regression, right?

Nevertheless, I still think that merging new drivers as fast as possible
is a good thing (tm).
