On Genode, the current drivers for the Pandaboard comprise USB (for HID and networking), HDMI, and SD-card. There is currently no driver for the dynamic voltage and frequency scaling (DVFS) feature of the OMAP4 SoC. So I would just expect a higher power consumption of Genode compared to native Linux, which comes with a DVFS driver. That said, I see no real show stopper that would speak against implementing such a driver. The DVFS driver would run as normal Genode process like any of the other drivers. Are you interested in having a closer look on this topic? If yes, I would be happy to discuss possible approaches about how to integrate power saving features with the Genode architecture.
