If you look at my original post, you'll see that I described why it
doesn't work. The default service start order (I believe) is:
If network tries to bring up a wireless connection that uses
wpa_supplicant, it will fail. I'm asking if anyone ever somehow managed
to being up a wireless connection that uses wpa_supplicant when network
starts but before wpa_supplicant is started. I can't see how, but just
because I can't doesn't mean it's a bug. If nobody can then perhaps
it's time for a Bugzilla report. I'm just trying to be thorough.
BTW, I'm running kernel 188.8.131.52-107.fc8 and use the package
for the Intel Pro/Wireless 3945 in my Dell XPS 1710 laptop. I used to
use the atrpm packages. I've found that after resuming from hibernate I
sometimes need to restart (stop/start) wpa_supplicant before I can bring
up the wireless connection.
