  DisableSysfs false
are confusing.

  *
  *
  * By default, madwifi plugin enumerates network interfaces using /sys
- * filesystem. Configuration option DisableSysfs can change this to use
+ * filesystem. Configuration option `Source' can change this to use
  * /proc filesystem (which is useful for example when running on Linux
  * 2.4). But without /sys filesystem, Madwifi plugin cannot check whether
  * given interface is madwifi interface and there are private ioctls used,
  * which may do something completely different on non-madwifi devices.
- * Therefore, option DisableSysfs should be used together with option
- * Interface, to limit found interfaces to madwifi interfaces only.
+ * Therefore, the /proc filesystem should always be used together with option
+ * `Interface', to limit found interfaces to madwifi interfaces only.
