[PATCH] nvidiafb: Fix 6xxx/7xxx cards

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
Date: 2005-12-07 08:35:42

Recent X "nv" driver was fixed for various issues with modern 6xxx and
7xxx cards. This patch ports those fixes to nvidiafb. This makes it work
fine on the 6600 bundled with the newest G5 macs. I've verified it still
works on the 5200FX of the iMacG5.
