I thought I'd send the list a heads up if you are looking for a USB to JTAG programmer/GPIO/serial. We're using the FT4232H for our manufacturing process, and it's worked quite nicely. Port A - JTAG Port B+C - GPIO Port D - serial port It's supported in Linux 2.6.30+, using libftdi 0.16+, and openocd (not sure what revision you need for that, we are on svn 2824).
