Be aware of the following: If a recent NTP daemon detects an old NTP kernel
interface (like that of unpatched Linux), it will not use the NTP kernel interface
at all ("disable kernel"). Thus no leap second processing will happen (AFAIK).

Fight the real problem then: Update the kernel NTP interface to the current one
(which is several years old by now). It's named "nanokernel" by Dave Mills, and it
was exactly the reason why I had patched Linux 2.4 to provide a nanosecond clock
resolution (in theory), and I also thought that's the reason for having
nanoseconds with your patch set ;-)
