Are we talking about the same thing?  In IRC he specifically referrers
to GNOME and nm-applet.

[16:20:24] -*- jnettlet bearer of bad news.
[16:20:41] <jnettlet> I have returned and I believe my wifi is dead.
[16:21:26] <cjb> that's excellent news; we have a reliable test case now ;-)
[16:21:35] <cjb> (wad might not share my opinion of its excellence.)
[16:22:48] <jnettlet> cjb: but this may be software/firmware related.
I explicitly disabled the wifi card through nm-applet in GNOME, and
suspended the machine by closing the lid.
[16:23:13] <jnettlet> somehow I think sending the rfkill to the card
puts it in a state that is susceptible to getting zapped
[16:23:20] <cjb> ooh
