Steve,
you do have to wait more than an hour before deciding to re-post the question.
Most people login only once a day, some only login weekly.
Also, bear in mind that as there are users from all over the world statistically many of them wil be asleep/at work/having sex/doing something far more enjoyable, at any given time you choose to post.
The converse is also true, I have had a question answered almost immediately when I posted it a 03:00am my time, but mostly they just ignore me completely, or hurl abuse/pocket pc\'s at me.
Anyway, to partly answer your question, I haven\'t got that particular gps card to work with a zaurus, but I have got a gps card that both sharp and the manufacturer claim do not work, to work on not one but two zauri(see my sig).
But don\'t expect the software that comes with it to do any more than take up space on your cf card.
