[PATCH] sstfb: add sysfs interface
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
