No special firmware or driver is required. Just as long as the driver supports the feature. > I've noticed a patch related to this issue, published on > 2012-01-27 by Christian Lamparter.

That's probably too old. The patch you are talking about is not a -stable patch so it's not backported to 3.3.x (or older) kernels. So, either you can upgrade to 3.4, use compat-wireless <http://linuxwireless.org/en/users/Download/#Getting_compat-wireless_on_Ubuntu> or backport the patch yourself (however, this could be diffcult).
