For the test i changed the kuserdata address in ntdll and kernel32 to 0x70000000
Vincent, as there are screenshots running the same binary on a RT tablet i would they the shared user data is handled the same
as on i386, thus no need for you to test it, sorry for the noise.
Here is the backtrace (asking for PF_SSE3_INSTRUCTIONS_AVAILABLE i think):
Unhandled exception: page fault on read access to 0x7ffe027e in 32-bit code (0x0040101c).
