I think I'v tracked pretty much every thing down and that I can merge these
patches. Will take some hand work, but .. so what.
I do have a questions about one thing in the include/asm--i386/segment.h
file. This changes the layout of the per-CPU GDT rather substantually. Is
this likely to poison Xen?
below in the relevant patch:
