Rick's comment makes sense to me, better just to provide the latest
version. No need to unnecessary confuse the users. And if someone really
wants to use an older version that she can retrieve it from the git
history.

So iwlwifi now has:

	  In order to use this driver, you will need a firmware
	  image for it. You can obtain the microcode from:

	          <http://wireless.kernel.org/en/users/Drivers/iwlwifi>.

Maybe that could be changed to mention about the wiki page in general:

	  The driver has a wiki page at:

	          <http://wireless.kernel.org/en/users/Drivers/iwlwifi>.

But I know iwlwifi updates the firmware images pretty often so Emmanuel
might see this differently.
