Hi Ton, sorry, but I can only offer a "me too" message: I had the identical problem with my 1.2GHz GigaDesigns card which eventually went belly up so I RMAed it (they replaced it with a new 1.4GHz card (alas, which won't sleep, but I can live with letting the displays go black and the disks spin down)).
