 :-)

 Modules use a separate set of variables with _MODULE appended to their 
names.  Thus for an option FOO, you'll get:

#undef CONFIG_FOO
#undef CONFIG_FOO_MODULE

if it's set to "n",

#define CONFIG_FOO 1
#undef CONFIG_FOO_MODULE

if it's set to "y", and

#undef CONFIG_FOO
#define CONFIG_FOO_MODULE 1

if it's set to "m".  Individual tests may check these both as they find 
appropriate.
