Impacts of disabling Automatic Power Management

Disabling suspend during collaboration was discussed a year ago, but as far
as I know this has not made it into any 11.3.x build:
There might be a few 10.x.x builds with this change but I would have to
research this to confirm one way or another.
I could easily see USB GSM modems being unhappy about repeatedly losing
power, as my USB CDMA modem resets itself every time that happens. This
then requires it to reacquire a connection to the tower, reset the
computer's PPP link to the modem, etc. This may require the XO to stay
powered on via a usb-inhibits rule, network manager script, or Sugar's
GSM/NM monitor whenever the connection is active.
But unless the GSM/3G connection is being used to contact a school or other
collaboration server I think these are two independent problems.
