Sure. I made my changes on top of your older patch. I studied your old/new
patch over and over. I had to slightly adjust it as your new patch does not
100% match the current cvs code. If you like I send you my full i386-tdep.c
(it is quite fat - so I do not attach it now)

Would it help if I make a simple plain c example (source + executable code)
which you can step thru on your own? If you have the time to do so...
