This is pretty surprising. 

The -ve segment emulation stuff should be able to handle all the
different forms of tcb and tls access we know about.

What happens if you don't move tls out the way? It'll be slower,
but should work. (is it falling back to 686? -- "ldd /bin/sleep"
will tell you).

What glibc version is it using?

Can you get a debugger to look at the operands to the faulting
instuction.

Thanks,
Ian
