Changes (by Quozl):

  * next_action:  diagnose => add to build


Comment:

 Was fixed in Q4B10, broke in Q4B11 due to svn 2561, fixed in svn 2680,
 will be included in next release of OpenFirmware.

 Developer release available for testing
 [http://dev.laptop.org/~quozl/q4c04jc.rom q4c04jc.rom] built 2011-11-10
 01:02:38.

 There is no need to hold the button down in testing, however if you wish
 to do so check first that the power LED does not flicker.

 As an additional precaution, one may check to see if the fix is present.
 On Q4C04jc and later, the following output shows the fix is present:
 {{{
 ok see flash-vulnerable(
 : flash-vulnerable(
    ignore-power-button hdd-led-on
 ;
 ok
 }}}
 On Q4C04 and earlier, the following output shows the fix is absent:
 {{{
 ok see flash-vulnerable(
 : flash-vulnerable(
    hdd-led-on
 ;
 ok
 }}}

 This check is relevant only to the firmware version performing the
 reflashing.
