But that's the point, if you go to the compatibility matrix it says there is a native driver and it should be working. It's just not. If you look at 6.7 it says it was there then as well.....just it obviously wasn't using it. If you read the forum above someone tried to force it to native in 6.7 without luck.
Are you using the prescribed driver version? If so, you may want to open a case with GSS. It's also possible that this list isn't accurate for 7.0. Since it's such a new release, there are (and will be) things that are mistakes which are getting corrected.
