I will present the current state of affairs during the BSDDay(2011) in
Bratislava.  The project has evolved quite a good bit.

I am not calling it Lunatik anymore, but "Kernel mode Lua" or "Lua in
the NetBSD kernel", and I added the missing pieces.  I think there is
now a whole infrastructure to use Lua in the kernel.  Let's discuss it
in Bratislava.
