ffb is a UPA based color frame buffer, found in some
  Sun SBus and PCI systems. The ffb driver supports both
  the Creator/Creator3D, and the Elite3D frame buffers.
There are several versions of the ffb
    board. The Sun part numbers and board types are:
The ‘Creator’ cards have 5MB of on-board memory, support a maximum graphics resolution of 1280x1024, and are single-buffered.
The ‘Creator3D’ cards have 15MB of on-board memory support a maximum resolution of 1280x1024 double-buffered, and 1920x1360 single-buffered.
The ‘Elite3D’ cards have 15MB of on-board memory, support a maximum resolution of 1280x1024, and are always double-buffered. The ‘Elite3D-m3’ cards have one hardware geometry engine, whereas the ‘Elite3D-m6’ cards have two.
The ‘Series 3’ cards are considerably faster than the ‘Series 1’ and ‘Series 2’ cards.
The ffb driver supports reading
    EDID data from connected monitors on ‘Series
    2’ and ‘Series 3’ cards, and will automatically set a
    resolution that is supported by both the card and the monitor if the
    EDID data can be read. This can be overridden for
    the console frame buffer, by setting the
    output-device openprom variable. For example, the
    following openprom command will set the console resolution to 1280x1024 @
    60Hz, which will not be altered by the ffb
  driver.
setenv output-device screen:r1280x1024x60
EDID data.
The ffb driver does not support 3D
    acceleration.
Not all 13W3 to
    VGA converters connect 13W3
    pin 2 to VGA pin 9. This pin supplies +5V DC to
    power the monitor EEPROM, even when the monitor is
    powered off, and is necessary in order to obtain
    EDID data on some monitors.
