The framebuffer driver as a whole is incomplete, and won't work as a
frame buffer driver. If someone were to correct that, that would be a
Good Thing (tm).
I wrote the driver for use on the Embedded Planet Icebox (Sensoray 322
module). I was primarily using the XFree86 siliconmotion driver, but
this makes some PCish assumptions. I wrote the framebuffer driver to
do the basic initialization of the card - with the fb driver loaded
it's relatively easy to get X working. I intended to complete it -
i.e. make it a fully working fb driver, but I never had the time.
Note that the fb driver does do one particularly important thing - it
initializes the memory subsystem using some undocumented prodding of
the card. On PCs this is performed by the card BIOS, and the video
memory won't work correctly without it.
