Please tell me if it isn't. I'd love to get feedback from someone with specs for those AGP chipsets, or someone with a v3 card, on the other half of the patch in the PR.

I'm very interested in getting these stability issues fixed. -- Eric Anholt eta@lclark.edu http://people.freebsd.org/~anholt/ anholt@FreeBSD.org
