Slackware is typically not patching much (and I'm just using the
pre-compiled binary). Here is the link to how it's built:
http://slackware.osuosl.org/slackware-current/source/d/gcc/
there doesn't appear to be anything relevant changed.

I already posted the .s files, plain 2.6.36 and the one with working
patch, I =think= that's already using -fverbose-asm, at least that shows
in the output.
