Right now, No FreeBSD version that I'm aware of supports 16650 software selection of baud rates higher than 115.2kbps. I plan on rectifying this, but that certainly won't be anytime in the next month or so. However, some of the ByteRunner cards allow you to feed a higher than standard clock to the UART. This doesn't have to be supported by software, as the software will set 115.2kbps and get 2 or 4 times that. I understand that there are some kernel tweaks that need to be done to make this work reliably. I've got some cards I'm going to play with, but I haven't actually set them up yet.
