-	  This driver supports graphics boards with the nVidia chips, TNT
-	  and newer. For very old chipsets, such as the RIVA128, then use
-	  the rivafb.
-	  Say Y if you have such a graphics board.
+    Supports NVIDIA GPUs from TNT through early GeForce generations
+    (NV4â??NV2x: Twintor, Twintor2, Celsius, Kelvin).
+    Later architectures (Rankine and newer) are not reliably supported.
+    If unsure, say N.
 
 	  To compile this driver as a module, choose M here: the
 	  module will be called nvidiafb.
