at the moment (2.6.13-rc4) ftdi_chars_in_buffer() unconditionally return

I don't think so, but it shouldn't really return zero until all write
URBs currently in-flight have completed; in other words, all outstanding
write data has been sent to the UART. This is what the "normal" serial
drivers do; they don't wait for the UART's transmit FIFO to drain.
