There are two things we can check for 2SG1 cards, firstly, are they listed in the devices list:

  ls -l /dev/dri
  
  This should return an output similar to the following:
  
  card0
  card1
  card2
  renderD128
  renderD129

Having no return from this is obviously quite bad.

Secondly we can check for the hardware using the following (I believe this relies on pci-tools being installed)

  lspci |grep SG1
  
  This should return an output similar to the following:
  
  1a:00.0 VGA compatible controller: Intel Corporation SG1 [Server GPU SG-18M] (rev 01)
  1f:00.0 VGA compatible controller: Intel Corporation SG1 [Server GPU SG-18M] (rev 01)

There are two devices shown here and these are the SG1 chips, so a 2SG1 card has two SG1 chips, so you see two devices. If you have two cards installed you will see 4 devices.
