Comment(by rsmith):

 The brief RED flash before a retry of the boot is the EC timing out
 watching for MAIN_ON to assert OR for PCI_RESET# to de-assert. Issues we
 had with the ATest series of board and thought to be solved.

 Its orange sometimes because either the the EC is also trying to charge
 the battery or its full.  Both cases would turn the green LED on.

 (I just updated the EC code to do a double flash on PCI_RESET timeout so
 in future you can tell the difference and to turn off the green LED so it
 should just flash red.)

 Try the following test:

 Edit your olpc.fth in the /bootpart/boot directory and replace the word
 'boot' with the words 'd7 ec-cmd66'.

 You can also edit the file directly from OFW with:

 ok emacs int:\boot\olpc.fth

 This is a special EC command that will make the EC simulate a power off
 and then a power on. Turn it on when its cold and let it sit rebooting for
 about 10 or 15 minutes see if it happens again.

 Then hit 'esc' to stop at the ok prompt and run

 ok test /cpu many

 The when the back cover feels good and hot break out of the above (by
 hitting a key a few times) and re-run the above test by either typing
 'bye' or power cycling or by another 'd7 ec-cmd66'.
