The game seems to use the same malloc and free functions, so I was able to
modify them.

I'm attaching a 7z file containing the diffs files to apply to swkotor.exe to
do the double mallocs and to disable the free function.

The game still crashes at the same location, so I guess it has nothing to do
with memory allocations.
I noticed 2 things however: the crash is always at the end of the loading,
which is where some large textures are allocated and pbuffers are used. This
used to be a problem with Mesa, although they seem to have fixed it over a year
ago. In the terminal it says something about a WGL function being a partial
stub, could this be the problem?
