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.
Thanx, Paul
