Ok this is a doosey and complicated bug.

It seems in a recent mod to ntfs-3g opengl apps will bomb out causing a page
fault at first I thought it was the kernel then the new lib32 packages on
gentoo then I thought it was the new nvidia 32bit libGL libs, then I thought it
was kernel switches... none of it made much sense because things like winecfg
and built in apps ran fine.

reference abandoned bug for more indepth pain.

I installed ubuntu and my problems went away so I thought it must have been a
gentoo issue. How wrong I was. I added my custom ntfs-3g stuff to the fstab and
boom on ubuntu I started having the problem, but when I let the OS mount the
volume I didn't get a page fault anymore.

Here's what I found.

Environment
libfuse2 2.7.0-1ubuntu5
libntfs-3g12 1:1.913-2ubuntu1
wine (pick your version I had it on every version from 0.9.36 -0.9.48 )
kernel 2.6.22 & 2.6.21 & 2.6.17 (those are the ones I've tested it on)
CPU is x86_64 don't know if this affects 32bit CPU's.

So there you have it, I can duplicate this issue easily and can provide more
information if requested. Bit sad that I blew away my gentoo distro but I never
would have figured this out without ubuntu.
