I've found when I was fooling around with powerd's code and blew it that
is what occurs, the video system doesn't switch from the DCON chip to
using the cpu.

Yes, the check-mark key turns the DCON off during boot, that is powerd
job to do once booted.

One of the first things powerd interacts with is the network card, I'd
run the OFW's tests for wifi. On one of the problem XOs, once in sugar
can you connect to an AP? Can you send me the logs from /var/log off
list to have a quick look at?
