-         This option enables thinkpad-acpi hot key handling over the input
-         layer at driver load time.  When it is unset, the driver does not
-         enable hot key handling by default, and also starts up with a mostly
-         empty keymap.
+         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.
 
-         This option should be enabled if you have a new enough HAL or other
-         userspace support that properly handles the thinkpad-acpi event
-         device.  It auto-tunes the hot key support to those reported by the
-         firmware and enables it automatically.
+         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 unsure, say N here to retain the old behaviour of ibm-acpi, and
-         thinkpad-acpi up to kernel 2.6.21: userspace will have to enable and
-         set up the thinkpad-acpi hot key handling using the sysfs interace
-         after loading the driver.
+         If you are not sure, say Y here.  The driver enables polling only if
+         it is strictly necessary to do so.
