[PATCH] sstfb: add sysfs interface

Browse source 
Modify the sstfb (Voodoo1/2) driver:

- fix a memleak when removing the sstfb module

- fix sstfb to use the fbdev default videomode database

- add module option "mode_option" to set initial screen mode

- add sysfs-interface to turn VGA-passthrough on/off via
  /sys/class/graphics/fbX/vgapass

- remove old debug functions from ioctl interface
