what exactly do you mean by "expansion port on the Omnima LCD display" ?
On the display that I've got there aren't any external ports except for JTAG. Well, there are also the 5 buttons

The LCD has a 2 GPIO/SPI expansion slot with the P0.17 and P0.18 pins from LPC2103 connected to it. See the attached picture.

A Samtec SMD 1.27mm pinheader and socket (FTS-104-02-L-DV and CLP-104-02-G-D) can be used to connect the Omnima PIC MAX or another daughterboard.
