I think the clue might be in the fact that grgry used his camera to format the card first? I can't think how this would make a difference when the image utility writes over the format structure though =/
There could be a genuine incompatibilty with certain cards, but there must be a reason. I wondered if it was to do with the number of bytes per sector or something? Also, I believe there is 'inaccessible' area of SD cards much like the Memory Stick from Sony. An area that can easily be read by certain hardware but not read using normal reader / writers.
It seems strange that these cards all adhere to the SD standard and work fine in thousands of other devices. Alternatively it could be a timing issue with the GP2X itself? I wonder if there is some time critical code that isn't written to handle the vast range of timing / tolerance differences between cards.
I might be able to shed some more light on this when mine arrives.
