The right time to press Tab is immediately after point 2. Try pressing
it several times quickly in order to make sure that the system
"detects" it. Then press tab slower (ie: slow enough for your monitor
to detect the resolution switch and start up). Never wait more than
10s between each key press though, as I seem to remember that the
system will go on booting if it doesn't detect any keypress after 15s.

If you have an LCD monitor, try using it. Those have almost no "heat
up" delay...
