Ok I have been testing apmsleep with my 6000l. If it is on battery power, apmsleep +00.05 does not work. The zaurus suspends but will not resume after 5 min. No errors when I do resume with the power button. Now if I apmsleep +00:05 and wait for the 5 min to pass, then put it in the cradle it will resume. If its in the cradle when i issue the apmsleep command it will not resume unless i remove it from the cradle and put it back, where it will resume when its put back. If its in the cradle, and suspended I can not ssh into it so I know its really suspended not just with a blank screen.
If any other test or info is needed please let me know.
-edit-
it seems to be power not just the cradle that is the important part.
