I have attached them to this email.

Honestly, I don't know. xorg-server is using libunwind because the
"--disable-libunwind" option hasn't been passed to the configure script,
but I don't know anything else. I'm not an Xorg developer and I don't
know that information.

Rename the existing MIPS port to MIPS64? Do you mean making a copy of
it, right?

MIPS32 o32 (o32 is the only ABI for MIPS32)
MIPS64 n32
MIPS64 n64
