Hold the presses. I didn't notice if anyone else has mentioned it, but there is now a product called "Embedded Pi" available at the element14 site. It's especially for this purpose. It has the header layout for Arduino shield, so you can directly attach RAMPS 1.4 to it, with the SD/LCD package and all.

That should speed the porting process! The price is US$39
Depending on the jumper placement on the Embedded Pi, you can select each of the three modes of operation:
STM32/Standalone Mode: The Embedded Pi works as a base platform, the STM32 controls the Arduino™ shields directly without the use of Raspberry Pi. It can interface with outside world and can control surroundings by sending & receiving input/output using wide variety of sensors; like controlling lights, motors, and other actuators.
A quick & easy embedded project can be built in C using CooCox development tools, a FREE and easy-to-use ARM development tool environment for Cortex-M MCU with flash programming & debugging capability (CoIDE, CoFlash, CoLinkEx etc), along with the integrated abundant reusable code shared by CooCox team and CoFans.
ST-Adapter Mode: The Embedded Pi STM32 controls the Arduino™ shields, and the Raspberry Pi works as the GUI or command line console to send commands/data to and receive data from Embedded Pi. This is an advanced mode which extends and strengthens the automation control capability of the Raspberry Pi, taking the advantage of STM32F103 NVIC (Nested Vectored Interrupt Controller), GPIOs, and more peripherals like ADC and PWM.
Raspberry Pi Mode: The Embedded Pi works as a hardware connection bridge between Raspberry Pi and Arduino™ shields, allowing the Raspberry Pi to interface directly with existing Arduino™ shields, having a number of sensors & control to interact with external environment. It offers all the possibilities of connecting digital and analog sensors using the Arduino™ shield but with the power and capabilities of Raspberry Pi.
