Comment:

 I suspect this is related to the wireless firmware, rather than network
 manager (but I could be wrong).  The wireless firmware hasn't changed much
 between 656 and update.1, but I'd guess the first step would be to try to
 reproduce this with an update.1 candidate and/or the latest joyride.

 Stephen, 'olpc-update joyride-1617' will give the latest joyride, which
 has wireless firmware 5.110.22.p1.  At the moment, the update.1 candidate
 has a slightly older firmware: 'olpc-update update.1-690' will give you
 5.110.20.p49.  The latest stable build 656 has firmware 2:5.110.20.p47.
 You can check your wireless firmware version with 'rpm -qa | fgrep
 libertas'.

 My suspicion is that none of these will actually solve your problem, but
 I'd like to be pleasantly surprised.  We're trying to figure out if
 5.110.22.p1 is enough of an improvement over 5.110.20.p49 to merit its
 inclusion in update.1 (even though we're in code freeze); clearly a report
 that one worked for you but not the other could inform that choice.

 If you find that none of these work, I'll expect we'll want logs against
 the latest firmware (the version in joyride).  dcbw and/or carrano can
 give you instructions there; I'm not sure exactly what logs will be
 useful.  If you can manually configure the network
 ('/etc/init.d/NetworkManager stop' and then 'iwconfig eth0 essid ....' and
 'dhclient eth0') that would tend to implicate NetworkManager; if not even
 manual configuration will work, it would implicate the firmware and/or the
 kernel driver.

 (Actually, since your problem is that it doesn't show up in the network
 view, the output of 'iwlist eth0 scan' would be useful as well -- does it
 show up there, by any chance?)
