Just one question: have you checked the page table setup for the
basics wrt the USER bit in particular?

No global pages should be marked PAGE_USER, with the possible
exception of that nasty old vsyscall page.

And it would be nice to verify that the page tables for kernel
mappings also don't have PAGE_USER on them, although again that
vsyscall page can cause problems.
