It's possible, but not very effective use of routing area with DIP 40. A 100 mils square PGA (pin grid array) would be better. It's just as easy to prototype as a DIP.

Starting with 1 million gates XC3S1000.

Hi,

thought I would post another real answer to the original question, not
some phantasy posting about  1Mio gates FPGA.
Have a look here:

What do you mean by phantasy? There are actual soft ARM cores in 200K, PPC cores in 300K FPGAs. What do you think the micro manufacturers use for prototypes? 1M gates FPGA is mid-range. 5M gates can be yours, if you send us a cashier check.

These are also nice. Thank you! I agree, there seems to be tendency to overkill. The whole ARM core is 30k transistors; 1mil gates FPGA for $hundreed(s) just to immitate ARM core for 5 bucks ... nonsense Anyone selling an ASIC, something like AT91SAMX but bundled with PHY ?

Impossible to do it in 30k. Unreasonable to buy FPGA with less than 200k. You are the one asking for FPGA. Have you find any ARM with FPGA for less than $100? You are not only asking for ARM, but ethernet, Sdram, CF and custom FPGA gates. Have you guys really look into the FPGA market?
