Changes (by Quozl):

  * next_action:  diagnose => design


Comment:

 Work in progress.

 Reproduced without using ''menu'':

 {{{
 ?open-mouse  200 200 true update-position
 draw-mouse-cursor remove-mouse-cursor
 s3-selftest
 draw-mouse-cursor
 }}}

 After the last command, observe the display and note the cursor state.
 For XO-1.75, the cursor reappears.  For XO-4, the cursor does not appear.

 Workaround after ''s3-selftest'':
 {{{
 arrow-cursor 0 h# ffffff " set-cursor-image" $call-screen
 }}}

 Register dumps from the display controller show all the hardware cursor
 registers are cleared by the suspend and resume.

 Theory: XO-4 suspend test does not leave display controller powered but
 XO-1.75 does.
