Hopefully not after reading the mail that I just sent to you...

No. It's not being exported so that you can't do what you just asked
to do ;-). Nor can you do nasty bodges replacing syscalls at runtime,
which is a nasty nasty hack unless you have to patch up against a
security exploit, but in that case you can come up with even nastier
and more cunning hacks to bodge in jumps in the running kernel.
