I agree, it would have been much better if you had communicated that before 
Pavel made the new revision. We'll put it on the list of changes for the next 
revision (rev04).

As a workaround, you can get 3V3 from a number of the other pin headers 
nearby. The FPGA JTAG has it, the Battery connector has it, the AVR GPIO 
header have it.

That's a really good idea, wish you had mentioned it earlier =).
