General remarks about this series:

- Please do not add code with '#if 0' and activate it later. This shows
  the series has the wrong order.
- Please refrain from basing your internal functions around 'struct
  device_d'. By doing so we completey lose type safety and at least in
  case of the mci framework where three different devices are involved
  this leads to unreadable and error prone code. The framebuffer
  code should be based around struct fb_info.
- Please keep the line lengths within sensible limits.
- Get rid of CONFIG_VIDEO_DELAY_INIT and make the mode runtime
  changeable. All this requires is a
  host->fb_disable(info); host->fb_mode(info, newmode); host->fb_enable(mode);

Sascha
