[PATCH] Unified lguest launcher
This is a new version of the unified lguest launcher that applies to
the current tree. According to rusty's suggestion, I'm bothering less
to be able to load 32 bit kernels on 64-bit machines: changing the
launcher for such case would be the easy part! In the absence of
further objections, I'll commit it.
