Oh for reference:
"To enable configuration registers programming, entry key must output 
twice to index port continuously. The entry key is decided by power on 
setting pins RTS2#/PS_CONF_KEY1 and RTS3#/PS_CONF_KEY0 as following:

RTS2#/PS_CONF_KEY1 RTS3#/PS_CONF_KEY0 Entry key
0                  0                  0x77 ( default )
0                  1                  0xA0
1                  0                  0x87
1                  1                  0x67

0x67 was the winner for me :-)
