Unfortunately this driver has suffered bit-rot upstream since the chip-
set is ancient and not widely used, and support for it in the 12.04 and
14.04 releases is poor to non-existant.

Marking as "Won't Fix" since we haven't found the expertise to fix it in
7 years.

Title:
  Silicon Motion X driver fails to correctly restore text mode; requires
  modprobe vga16fb fbcon

Status in xf86-video-siliconmotion:
  New
Status in xorg package in Ubuntu:
  Won't Fix

Bug description:
  Binary package hint: linux-source-2.6.22

  After installing from i386 Alternate CD (20070921.1) onto an Acer
  Travelmate C104TCi (C100), the PC has no console video driver and
  therefore virtual consoles aren't usable when switching away from GDM.

  The reason is, there is no console video driver loaded. lsmod doesn't
  show a module loaded.

  Alt+F2 "sudo modprobe vga16fb fbcon"

  in a terminal fixes this for the session. To fix it permanently the
  initrd image needs updating:

  $ sudo sh -c 'echo "vga16fb\nfbcon" >> /etc/initramfs-tools/modules"
  $ sudo update-initramfs -u

  After a reboot the consoles are usable.

  This should have been installed by debian-installer.
