Re: [PATCH] [AGPGART] intel_agp: fix GTT map size on G33
Subject: [PATCH] [AGPGART] intel_agp: fix GTT map size on G33 G33 has 1MB GTT table range. Fix GTT mapping in case like 512MB aperture size. Signed-off-by: Zhenyu Wang <[EMAIL PROTECTED]> Acked-by: Dave Airlie <[EMAIL PROTECTED]> Ditto. What happens if this patch isn't in 2.6.23? And is it applicable to and needed in 2.6.22? It's support for new hardware enablement, so maybe stable requires it, but I'm not sure how widespread this hw is yet..
