CUDA Wrapper err:module:import_dl

Alright, I'm stumped and everyone else is too. Few years ago we did
everything we are doing now and it all worked fine. Now using wine 1.2rc2 we
can't get a wrapper I compiled to work. What this wrapper does is it
translates/wraps the calls made to the cuda runtime dll (cudart.dll or
nvcuda.dll, same file different names) and sends it to the linux library.
The linux library and windows are identical except for some missing dx
functions in the linux library. My sources can be found here.
http://shelnutt2.host56.com/cudart/ and
http://shelnutt2.host56.com/cufft/(However we aren't even getting to
the second dll yet). Anytime we try to
run folding at home in wine, we are getting the following. FAH checks for
nvcuda.dll first because that comes with the driver installs on windows, if
it doesn't find it, it defaults to cudart.dll which is packaged with fah, or
can be installed separately. We have replaced all the cuda dlls with the
compiled wrapper or sum linked to the compiled wrapper, just like we use to
with the original cuda wrapper that we came up with.
err:module:import_dll Loading library nvcuda.dll (which is needed by
L"Z:\\home\\sidicas\\.FAHGPU3\\FahCore_11.exe") failed (error c0000020).
err:module:import_dll Loading library cudart.dll (which is needed by
L"Z:\\home\\sidicas\\.FAHGPU3\\FahCore_11.exe") failed (error c0000020).

More thorugh testing has been done,
http://foldingforum.org/viewtopic.php?f=54&t=14673&start=105#p146177 . When
we makes reference to gpu2 wrapper, that is our original cuda wrapper
designed for cuda 2.0-2.2 built couple years ago. The GPU3 wrapper is what
we are having problems with. It is our cuda 3.0 wrapper. The .dll files are
in the folder (we even tried in system32), ldd shows they are properly
linked, yet it does not work. If we use the old wrapper compile before it
works fine with cuda 2.x or with cuda 3.0 we just have to sym link the cuda
lib to the old name it's expecting.
I've tried compiling the old wrapper and linking it to cuda 2.3 however this
fails. So I am thinking that if when I compile the old wrapper which is
shown to work (when an old compiled version is used) but does not work when
I compile on my funtoo box it must be some weird compiling issue. I have
wine installed (without 64bit support), and I installed cuda runtime from
nvidia's site as the one in portage installs to /opt/ and I wanted to make
sure there wasn't any weird issues linking with that.
I do get a few warnings when I compile but they aren't anything that would
effect this.

If anyone has any ideas about why this doesn't work, that would be great.
I've exhausted everything I could think of.
Thanks,
