As for your note about the 'uname' issue -- we were considering wrapping 'uname' with a script that uses the kSplice API to query the effective kernel version. It would not be as effective as having the actual uname() system call return the effective version, but in our case it would satisfy our auditing tool, which runs in userland as a script (and thus doesn't make uname() system calls directly).

Have you had any experience with the kSplice API?

This is exactly what we do; we have a script that calls the Ksplice Uptrack API to get the "effective_kernel". Ksplice provides Python bindings but one of our guys released Perl bindings as well: http://search.cpan.org/dist/WebService-Uptrack

We've been running Ksplice in production for a few months on a dozen or so hosts. So far it works as advertised.
