No patch, but some hints - I suspect the problem is a local build config error...

1) The exact patch causing your problem in -mm1 is:
remove-register_ioctl32_conversion-and-unregister_ioctl32_conversion.patch

Building with this one patch -R'ed out should help, but it's the wrong thing
to do, as it only papers over the real problem, which is:

2) Your failing code is in os-interface.c:

void NV_API_CALL os_unregister_ioctl32_conversion(U032 cmd, U032 size)
{
#if defined(NVCPU_X86_64) && defined(CONFIG_IA32_EMULATION) && !defined(HAVE_COMPAT_IOCTL)
    unsigned int request = _IOWR(NV_IOCTL_MAGIC, cmd, char[size]);
    unregister_ioctl32_conversion(request);
#endif
}

Might want to figure out why HAVE_COMPAT_IOCTL isn't defined - there's at least
3 other places where it matters (in nv.c).  It's #defined in the include/linux/fs.h
header in 2.6.12-rc6-mm1, so you probably want to figure out why your build isn't
picking up on it.  Are your #include directories screwed up?

Sorry I can't provide more help, this looks like an X86-64 only issue.  If this
isnt enough, take it up on the NVidia forums:
