Dear Weidong,
A big big thanks for the vga passthrough patches for xen
3.5-unstable!!! These are eagerly anticipated patches. As I did not
study computer science and computer architecture, I won't be able to
write those patches you guys at Intel wrote.
I applied the following patches xen-gfx-passthrough.patch
and qemu-gfx-passthrough.patch
to xen 3.5-unstable without issues.
Then I tried to apply the 3rd patch you provided at
http://lists.xensource.com/archives/html/xen-devel/2009-08/msg01047.html
I saved the following code

as intel-gfx-passthru-patch-3.patch and then I tried to apply the patch to xen 3.5-unstable. I got errors. I think it's because the 3rd patch you provided is incomplete.
Here's my patching process:

Perhaps you should have used the -p or --strip option?

This patch supports basic gfx passthrough on QEMU:
- disable emulated VGA adpater if there is passthroughed gfx
- register/unregister legacy VGA I/O ports and MMIOs for passthroughed gfx
