+         Wide tnodes are only used for large NAND arrays (>=32MB for
+         512-byte page devices and >=128MB for 2k page devices). They use 
+         slightly more RAM but are faster since they eliminate chunk group
+         searching.
+
+         Setting this to 'y' will force tnode width to 16 bits and make
+         large arrays slower.
