My devlist.txt file is traight from VPN repo.
I have this for the device:

http://sourceforge.net/p/xc3sprog/code/HEAD/tree/trunk/devlist.txt
line 84:

02ad6093     10  0x3c9 XC5VLX110T

The ID of the corresponding jtag loc. 4 is:
0x72ad6093
BTW, why all IDs in devlist.txt begin by '0'? Reserved usage?

Also in devlist.txt:
05059093     16   0xfe XCF32P
Only the last 3 digits match... IMHO there is a potentially serious
issue somewhere.

I noticed there is a program 'detetchain' shipped with xc3sprog. So i
run it:

[adrien] > detectchain -c xpc
JTAG loc.:   0  IDCODE: 0xf5059093  Desc:                         XCF32P
Rev: O  IR length: 16
JTAG loc.:   1  IDCODE: 0xf5059093  Desc:                         XCF32P
Rev: O  IR length: 16
JTAG loc.:   2  IDCODE: 0x59608093  Desc:                      XC95144XL
Rev: E  IR length:  8
JTAG loc.:   3  IDCODE: 0x0a001093  not found in 'built-in device list'.
JTAG loc.:   4  IDCODE: 0x72ad6093  Desc:                     XC5VLX110T
Rev: G  IR length: 10

There we have the FPGA :)
