I am trying to implement the UART module to the Virtex5 ML506VSX board. Could anybody tell me how to set the constraints for the RS232 port in the UCF file. What is the FPGA Pin name? Thank you very much.

You really don't need any timing constraints for these pins, RS-232 is too slow to pose a timing risk.
The pin locations and IOSTANDARD are unchanged from the reference design .UCF file
What is the FPGA Pin name?
The board schematic (page 2 and page 12) show the board signal names and FPGA package pin assignments.
The .UCF file ties the design code signal names to the package pins locations.
With the board schematic and the .UCF file, you have all the information you need.
The .UCF file is in the reference design .ZIP archives.
