Hmmm... <checking the schematics>

Yes, it does. :) This makes perfect sense.

My bootloader (U-Boot 2010.03) doesn't seem to detect it, though:

Probing for expansion boards, if none are connected you'll see a

No EEPROM on expansion board
<clip>

Do I need a special bootloader?

Is there any standard way to recognize the expansion board and configure
it properly?
