I'm OOO until Thursday however, I could test this out on a Galileo for
you with the CSH stripped out. As Jan has pointed out Galileo aka Quark
x1000 non-secure (not to be called insecure) will just skips past the
CSH anyway - so - we can give it a conformant capsule by stripping the
CSH junk off the top.

How about you queue it up and I'll let you know if there's a problem
Thursday?
