Okay, somehow (despite being a clueless newbie to Open Zaurus), I managed to install the required ipks to get a steady green light on my Sandisk Connect Plus card! I am very happy.
If someone could help me figure out how to install ipks properly with "linkage" that works, I would be supremely happy.
The ipks seem to be installing in an odd place - media/card/packages/opt/QtPalmtop...at least I think the "packages" folder is odd and I can't find OpieMail at all in files manager searches even though I installed it. OpieReader, ZUC, Email and Opera have icons which do nothing when clicked on.
I have a 64-0, Opie install on a 5500.
Thanks for any help.
