On pandaboard.org you will find the Omap4 reference manual. This contains all the bits and pieces you need. Writing a framebuffer driver for the Pandaboard includes multiple steps. First you need to power on all required subsystems (HDMI, display). Then you will need the GPIO subsystem to configure the involved components (e.g. DDC). Configuring the framebuffer itself consists of only a few steps, however they may be hard to grasp from the manual.

Best,
Matthias.
