There are 4 ARM systems I can try that with - A Zaurus 6000, which is a PXA 255 - A Zaurus C860, which is also a PXA 255. - An Acer N30, but it's a s3c2410, which is quite different. - A Simpad - however it is a SA 1100, which has no HWUART. Moreover, its bluetooth module needs some reflashing (which I can't do). It is on ttySA1 - cf http://www.guylhem.net/r-hardware/simpad/bluetooth/ for the hardware part, http://opensimpad.org/index.php/Simpad.c for the software part. > For a PXA system we may help you out if you insist.

On the Zaurus 6000, I didn't add the module myself, but I think it's on 3.3 V directly. It is also on the UART that can be rerouted to HWUART (FTUART ?) On the C860, it is directly soldered to the UART lines - yet to ones of the standard serial port - ttyS0, which I think is STUART (will check tonight) and which can not be rerouted to HWUART IIRC. The demo could use either a 2.4 or 2.6 kernel. I usually run a 2.4 on the 6000 and a 2.6 on the 860 but that's only for tests. On the N30, I really don't know the s3c2410 - bluetooth work fine with a 2.6 kernel. Tell me if you need more information.
