New description:

 suspend/resume itself seems to work correctly, via /sys/power/state, from
 either Terminal or a VT. however, in the case of using a VT to commence
 the suspend, on resume a) the screen often flashes and loses data, and b)
 sometimes many 30 or more) extra shell prompts are produced.  it looks as
 if the enter key which was used to finish the "echo mem" may be repeating.

 this was os41 (the second version) and q3a16 on a B3.

Comment(by Quozl):

 Reproduced with a B2 on os57 using text console vt1 and:
 {{{
 echo mem > /sys/power/state
 }}}
 then pressing a mouse button to resume.  Sometimes the spew is before
 suspend, often it appears on resume as well.
