Subject: [PATCH] [AGPGART] intel_agp: fix stolen mem range on G33

G33 GTT stolen memory is below graphics data
stolen memory and be seperate, so don't subtract
it in stolen mem counting.

Andrew I meant to upstream these for 2.6.23 but travelling is still in progress, so if you could send them to Linus...

When looking at a "fix" I need to work out whether it might be needed in
2.6.23.  But your description of this patch didn't describe the problem
which it fixes in a way which allows me to decide this.
