You need synchronized versions of ISE and EDK.
ISE 4.2 => MDK 2.2
ISE 5.1 => EDK 3.1
ISE 5.2 => EDK 3.2
And planned for september (thus november ...)
ISE 6.1 => EDK 6.1
And of course you also need the latest service packs installed for both 
ISE and EDK.

The mbvanillia platform made by John Williams is intended for Insight 
V2MB1000 board (including a 1 million gate Virtex 2 FPGA), but you can 
target other boards if you change the pinout (UCF file) accordingly. 
Insight has also Spartan2 boards as well.

The Xess board (i just look at it) should work, but it may be quite 
small in term of internal logic and internal/external memory ... you may 
not use any peripheral around the MicroBlaze ! Better to choose the 
XSA-100 if you want a Xess board, with twice SDRAM, Flash and FPGA size.

Avnet also makes eval boards for Xilinx FPGAs, and their Spartan II 150 
board is the same price than Xess' Spartan II 50 board, but it has no 
external memory.
