Glad I managed to exceed your expectations.  ;-)

Let's see...  When I do an allnoconfig build, it has CONFIG_PRINTK=n.
Given that this facility is based on printk(), I could create an
additional patch that #ifdef'ed everything out in CONFIG_PRINTK=n kernels.
This would uglify things a bit, but it would save ~300 bytes.

If I don't hear otherwise from you, I will put something together,
test it, and send it along.
