The VEX translator needs work to understand the segment prefixes (%gs, etc.)
and the instructions which tend the x86 segment registers.

I got valgrind+wine working enough on i386 to produce useful results
in some cases.  Patches were needed on both sides.  For starters,
see my series of 15 posts:

   [Valgrind-developers] valgrind(memcheck) + wine: patch 0/14 Summary and index
   07/09/2008 09:53 AM

and my wine patches archived in

   http://www.winehq.org/pipermail/wine-patches/2008-July/author.html

It seemed to me that not too many people, neither in the valgrind camp
nor in the wine camp, were enthusiastic about such efforts.
