I'm trying out the build on various different systems: knoppix, red hat, suse, 
debian.  In some cases running on borrowed machines, in other cases running 
on a knoppix boot cd.  (I care because I'm using the host tools, which vary 
slightly from system to system.)

You just suggested that I replace the kernels on all of these systems, 
(including other people's machines, and the bootable CD that uses a kernel 
with the cloop patch applied and an initramfs that's hard to extract) with a 
different kernel.  Just so I'm testing something faster that's not actually 
what I'm going to be deploying.

If I was going to replace the host kernel and run on a modified system, I'd 
just A) replace it with the version I actually need, B) run the build as root 
and use chroot instead of UML.

I'm interested in SKAS0 because it's potentially deployable.  Any SKAS that 
requires a modified host kernel is not, for my purposes.
