I deleted this fork for reconsideration.  The once-proposed patch is now here:
https://github.com/sugarlabs/sugar/commit/102dd5f2147a4ddb0ce516f2d1c5907defbbba93

I feel naive about the wireless stack and NetworkManager behavior
(which changed so recently).

For example,
How does the behavior change with rfkill?
How does it change with a removable wireless adapter like a USB or
PCMCIA device?

I had proposed looking for a cfg80211 holders in
/sys/module/cfg80211/holders/ in an earlier patch,
https://github.com/sugarlabs/sugar/commit/f58fec25809649fa06b1a57f1fa65dd606c676a0

This worked for an XO-1, but some systems may use nl80211 instead or
have drivers in ROM (see
(http://www.haifux.org/lectures/206/wirelessLec.pdf).

It would be good to have some guidance from the community of wireless experts.
