So  already entered mainline as commit dddd60220f41 ("ipw2200: select
CFG80211_WEXT"). As this revert has now been applied, I think my patch
should now be reverted too. But I don't think it's a good idea to submit
a patch, however trivial, in the last hours before new year. So I'll
have a look into this in the first days of next year.
