I followed the example of drivers/s390/,
per Linus' suggestion.

The other place that seemed to suggest itself was
arch/x86/drivers/, as we already have:

arch/um/drivers/
arch/sh/drivers/
arch/cris/*/drivers/

These are vendor-specific, aka "platform specific" drivers
for various x86 platforms.

> What is wrong with the current location under misc/*?

mostly that it "misc" means nothing at all...
Indeed, misc should probably be deleted for this reason...

is there an example besides lguest/x86?

+ default y
+ ---help---
+ 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.

+ It also adds the ability to switch camera/wlan on/off.

+ If you have an Eee PC laptop, say Y or M here.
