The software would be quite design-specific.
I can post one for the Sparkfun's Nokia5110 screen ( [www.sparkfun.com] ), but i have no idea if it's something common.
Making it a front-end for Sprinter/Marlin is straightforward - there is little intersection between the internals of the GUI and the backbone, you pass commands by sending them into the buffer, and it can use the SD card already.
The bootloader is firmware independent, and is nothing special - just google avr sd card bootloader.
No idea how to integrate it with the Arduino software, however.
I guess the initial question is kind of pointless, so i'll just dump the designs here, free for anyone to use.
The main board: [orbides.1gb.ru]
The streamlined 1.4 (classic L298+L297) stepper driver: [orbides.1gb.ru]
These are schematics in Eagle.
Important note - the main board schematics say 5 volt and 7805, but it's really 3.3V, or the SD card and the screen would fry.
The software it runs on: [orbides.1gb.ru]
Butchered version of Sprinter 1.3.something, and an SD card bootloader based on PetitFS FAT driver..
No heated bed controls in either - i have a separate circuit for it.
Feedback is welcome, btw. I have no idea how sane the PCB layout or the whole design is.
Finished up PCB.

Works nicely so far.
If no problems show up, then the machine is out of initial development stage, and into the infinite development one :)

One more note - don't ever attach a breadboard to anything with a lot of double-sided tape.
The damage is repairable, but it's still a mess:
