I'll wait until we get to consensus with Davem and I do the kernel side.

No problem. He will not do it. sparc64 userland will be officially supported
with 2.3.latest and later. E.g. up to 2.3.18 or when was it any 64bit task
can set its page tables as it wants because it can access its VPTE area, so
enabling BINFMT_ELF on those kernels is a security issue. Also, several
other bugs have been fixed in 2.3, so 64bit userland would not be usable
anyway.
Cheers,
Jakub
