I think there should also be a distributor for you, take a look at the
contact page:

I changed the mega8 to a mega48 because i wanted to run everything at 3.3
Volts, and the firmware was changed, too.
The init is a little bit different to the hd44780, and the EA-DOG has a
digital contrast setting.
You could take a look at my schematics:
I'll upload the atmel sourcecode and a more detailed description within this

If you aren't shure which backlight would look nice you could also use the
DOGM simulator found at the product page.
I don't have more information, but it looks like there are four leds into
the backlight panel. I could also send you high resolution pictures.
