In linux kernel since version 2.6.33.2 (release Date: 2010-04-01)  
This is the framebuffer device for the Sun XVR-1000 and similar
graphics cards. The driver only works on sparc64 systems where
the system firmware has mostly initialized the card already. It
is treated as a completely dumb framebuffer device.
