I had considered it but thought it would not be "kosher" to do it that
way. It would certainly be easier. If you think it is appropriate, I
will coalesce the two.

There are 6 pins behind the P9 header (right next to the 32.768K
crystal) which are connected to a ftdi chip wired to the am335x's UART0
pins. u-boot & openbsd use it as a serial terminal. An old USB ftdi
cable I had laying around worked:
uftdi0 at uhub5 port 4 configuration 1 interface 0 "FTDI FT232R USB
UART" rev 2.00/6.00 addr 2
ucom0 at uftdi0 portno 1
115200 baud/3.3V logic levels. Five volts will kill it, careful
