I always wondered why there is no "grey out", at least optionaly.

My "favourite"(tm) example of a sub-marine is: Wireless drivers (mac80211).

The config-option to switch on the visibility of the mac80211 drivers 
("CONFIG_MAC80211") is conveniently located on the other side of the 
milky way.
(3 menus down, a sitestep and 2 up again. At least in menuconfig)

Real Programmers consider "what you see is what you get" to be just as 
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated, 
cryptic, powerful, unforgiving, dangerous.
