  matrox g200eR2 is unclaimed in 14.04

Status in xorg-server package in Ubuntu:

Bug description:
  On a certified Dell PowerEdge T620 server

  The matrox video card is not recognised:
  lspci | grep VGA
  0a:00.0 VGA compatible controller: Matrox Electronics Systems Ltd. G200eR2

  lshw -C display
    *-display UNCLAIMED     
         description: VGA compatible controller
         product: G200eR2
         vendor: Matrox Electronics Systems Ltd.
         physical id: 0
         bus info: pci@0000:0a:00.0
         version: 00
         width: 32 bits
         clock: 33MHz
         capabilities: pm vga_controller bus_master cap_list

         resources: memory:d8000000-d8ffffff memory:deffc000-deffffff memory:de000000-de7fffff

  Thus xserver is not hardver accelerated.

  Also /dev/dri and /dev/dri/card0 is missing.

  kernel module mga is not loaded, although if i manually load by modprobe it works fine
  modprobe mga
  lsmod | grep mga
  mga                    40811  0 
  drm                   302817  1 mga
