Commit d0f3c7e41d30859a638083654002b9b6faf7f67b ("drm/nouveau: give a slightly larger pci(e)gart aperture on all chipsets") removed a test: that caused an 8x increase in gart aperture, instead of a 2x one, for on-board cards >= NV_40.

Hi, in Linux 3.5.x I experienced some crashes of the X server, and noticed from the boot that while the gart aperture in 3.4.x was 64MB, in 3.5.x became 512MB. So I came out with this quick patch: this seems to work, since X did not crash anymore (and I tried quite hard to), but I'm not sure if it is the right fix.
