No, I'm not. But I am seeing -ENOSYS from one of [gs]et_thread_area right
before things go haywire. But I haven't looked at it closely enough to
see if that's the real problem.
2.4 UMLs work fine with these libcs. I had been assuming (without any
evidence) that there was some other capability check (like uname), and
libc gets horribly confused when it sees a 2.6 kernel that doesn't have
the thread_info stuff.
If the compatibility check is -ENOSYS from one of those syscalls, then
this theory goes right out the window, and something else is wrong in UML.
