I don't appear to have the same problem with:
  -latest version of iwlwifi (0.0.35)
  - gentoo-sources-2.6.20 kernel (patched with a relatively old mac80211 package)

I believe fedora has 0.0.24 of iwlwifi embedded?
So the problem might have been fixed already.

Writing this email, after executing your command, when associated on a wpa2
network.
