+         Some thinkpad models benefit from NVRAM polling to detect a few of
+         the hot key press events.  If you know your ThinkPad model does not
+         need to do NVRAM polling to support any of the hot keys you use,
+         unselecting this option will save about 1kB of memory.
+
+         ThinkPads T40 and newer, R52 and newer, and X31 and newer are
+         unlikely to need NVRAM polling in their latest BIOS versions.
+
+         NVRAM polling can detect at most the following keys: ThinkPad/Access
+         IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
+         Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
+
+         If you are not sure, say Y here.  The driver enables polling only if
+         it is strictly necessary to do so.
