Why did you go for omap_4_-fb > driver, not omap-fb driver? I'm currently only having an omap4 board here. But I could rename the driver to the more generic name "omap-fb" and explain in the KCONFIG that it currently only covers omap4 devices. So we could go from there up to all other OMAP devices.
