I'm reviving this old thread, since I'm now facing the same problem with
the arrival of Mac OS X 10.6...

I consistently get the same error on 10.6, and it's the one with
unexec: unrecognized section name in __DATA segment
This unrecognized section in the DATA segment is called
"__program_vars", and I cannot find any documentation for it. It's not
mentioned in the Mach-O File Format Reference at all, even in the latest
XCode I installed from the Developer Connection.
So my guess is that unexecmacosx.c has to be patched to deal correctly
with that section. I don't know the first thing about this dumping
process, but I simply tried to include it in the section where
__la_symbol_ptr and __nl_symbol_ptr are handled, and it didn't work...
