BUG=chrome-os-partner:7428
TEST=manual

Switch to dev-mode, turn it on, see how long it takes.

With gbb.flags == 1 (factory mode), it should take 2 seconds.
(You'll see a warning on the screen if gbb.flags is nonzero)

With gbb.flags == 0 (after factory install), it should take 30 seconds.
You should hear two beeps at 20 seconds.
