Does anyone know the status of UART under Adafruit BBIOon Angstrom 09/04?

I just got started with the BBB and it looks like a really promising little unit. I have a pretty good experience with logic programming but I am very new to microprocessors. I was looking forward to using the BBB through its UARTs but I have had problems with the combination of the BBB, Python and the Adafruit BBIO routines. The problem seems to be with lost ( or not included) files under Angstrom 09/04.
