My setup (Fedora 18 32 bit, libusbx, libftdi, openocd 0.6.1) is very different from yours. The only thing I noticed that might be pertinent:
My machine didn’t even recognize the beaglebone until I used a very short USB cable. About 2’. Nothing at all from dmesg with a 6’ cable. With the 2’ cable openocd seems to work ok with the stock ti_beaglebone.cfg.
