I solved my problem by jumping JP7 to enable 5v on the board. I'd like
to note that this is opposite of what the manual says. Enabling 5v
allowed the RTC to work properly as well, without my hackish scripts.

I went through the hard way too. I never got to the point of trying
emdebian (although it looks great!), and managed to stumble onto some
information which led me to believe that the 7400 images work for the
7260.

I have the rough basics on how to get a sane setup documented here:
http://nuclear.unh.edu/wiki/index.php?title=Setting_up_an_SD_card_to_boot_from

It's really intended as an internal document, but this mailing list has
been a great help and it's easier for to post a link than to make a
generic guide.

Let me know if it works for you!
