-	  Say Y here if you have more than one (supported) Matrox device in
-	  your computer and you want to use all of them for different monitors
-	  ("multihead"). If you have only one device, you should say N because
-	  the driver compiled with Y is larger and a bit slower, especially on

-	  If you said M to "Matrox unified accelerated driver" and N here, you
-	  will still be able to use several Matrox devices simultaneously:
-	  insert several instances of the module matroxfb into the kernel
-	  with insmod, supplying the parameter "dev=N" where N is 0, 1, etc.
-	  for the different Matrox devices. This method is slightly faster but
-	  uses 40 KB of kernel memory per Matrox card.

-	  There is no need for enabling 'Matrox multihead support' if you have
