Oh, yes. It seems my email client had some good lunch with the tabs.

I added the patch as an attachment. Hope it works this time.

Subject: [PATCH] drm/nouveau: fix nv40 gart size

Nouveau sets GART size to 64MiB for all cards before nv50, but nv40 has
enough RAMIN space to support 512MiB GART size. This patch fixes this
value to make use of this hardware capability.
