Minimal Bitstream Size

I was interested to find out how much storage is needed to store the bitstream of a minimal design for a Spartan6 FPGA. The minimal design chosen is just a straight-forward 8-bit binary counter. The results are:

LX25
 Raw/Compressed: 801556/233934

LX16
 Raw/Compressed: 464290/134942

LX9
 Raw/Compressed: 340697/118773

The sizes stayed the same with and without CRC checking. Looks like the memory storage needed is between 8Mbits (raw) and 1Mbits (compressed).
