Subject: [PATCH] [Stable] agp/intel: complete the enablement for B43.1

This patch completes the missing part of commit 41a514 and 3dde04b and I think
commit 3dde04b is already in queue for next stable release.

Thanks Chris Wilson has the patch for enabling Intel B43.1 and backports it to
stable kernel. On mainline commit 210b23 and 1a997ff the way to detect gtt size
is changed, but these two commits landed on mainline kernel after .36 kernel
released. So that mainline kernel works fine on B43.1 machine but not stable
kernel.

Without this patch, X fails to start on 2.6.35.y kernel. After patched, X
starts.

This patch is made for 2.6.35.y and I believe it suits for 2.6.36.y.

I don't understand, is this patch upstream already? If so, what is git
git commit id for it? If not, why not?

confused,
