Daniel,

I put up a new patch that uses the unmodified vm_x86.c:

http://www.tjw.org/ioquake3-ub/ioquake3-svn801-default_vm_x86.patch

Build instructions:

svn co -r 801 svn://svn.icculus.org/quake3/trunk quake3.ub
cd quake3.ub
curl -O http://www.tjw.org/ioquake3-ub/ioquake3-svn801-default_vm_x86.patch
patch -p0 < ioquake3-svn801-default_vm_x86.patch
cd code/libs/macosx/
curl -O http://www.tjw.org/ioquake3-ub/libSDL-1.2.0.dylib
curl -O http://www.tjw.org/ioquake3-ub/libopenal.dylib
cd ../../../
sh make-macosx-ub.sh

Thanks.

-Tony
