	To get you up to speed, you may want to read these :

	The problem to resolve : two Pcmcia drivers with partial
hardware overlap. This happen quite often in the Pcmcia/Wireless
world.
	Basically, we want to offer fine grained control over driver
binding in a user friendly way and push that in distros. The basic
infrastructure is there (sysfs bind/unbind), what's missing is the
user friendly wrapping around (automatic on hotplug event, nice config
file, ...).

> Drivers binding to devices that they should not bind to?

	No, that's not what we are trying to solve.

>  Why are they binding to these devices in the first place?

	Because those drivers do support the device.

	I personally don't know what it does.
