Ahh.. ok. Right, it is there only for HDLC...

Anyway, the datasheet
http://www.datasheetcatalog.com/datasheets_pdf/S/3/C/4/S3C4510B.shtml
mentions that the serial port is able to do DMA, effectively
using the system memory as the FIFO. You'd need to write
a driver for this, but maybe this is the cleanest option.

Or a very slow baud rate.
