Good luck. I haven't gotten my hands on an n810 yet so I can't really try anything onhand.

One more suggestion though... neat thing about the micro/mini/SD cards is that they're pin compatible. It may be possible to hack something that will allow you to use a SD via the n810's miniSD slot with a dongle. There is a commercial solution out there, but I haven't managed to find a source for it in NAm... I've been considering a homebrew solution using wirewrap, a microsd to minisd converter and a sd breakout from sparkfun.
