-     Linux 2.0.x - For x<=31, using any variant of the adjtimex() call
-     sets the kernel into a mode where the RTC was updated every 11
-     minutes.  The only way to escape this is to use settimeofday().
-     Since we need to have sole control over the RTC to be able to
-     measure its drift rate, and there is no 'notify' callback to warn
-     you that the kernel is going to do this, I can't see a way to
-     support this.
-
-     Linux 2.0.x - For x>=32 the adjtimex()/RTC behaviour was
-     modified, so that as long as the STA_UNSYNC flag is set the RTC
-     is left alone.  This is the mode we exploit here, so that the RTC
-     continues to go its own sweet way, unless we make updates to it
-     from this module.
-
-     Linux 2.1.x - don't know, haven't got a system to look at.
