Thanks Jonathan. You're my hero! :) And I'm not being condescending!

everyone that's helped with my problems is much appreciated!

It doesn't exist for the edb7xxx (and cyg_io_lookup() should return an
error when you ask for it). The idea is to make the serial port numbers
in eCos be able to correspond to any physical markings on the board, in
this case UART 1 and UART 2 on the silkscreen.
