Hi Tim,

I have downloaded linux-2.6.18.8-xen source code. I am compiling it now.
If I still cannot get nVidia Geforce 8400 GS PCI-e x16 secondary gfx to
be passed through to Win XP HVM dom U with xen 3.5-unstable with intel
gfx passthrough patches applied with xenlinux 2.6.18.8, I will give up
the attempt on the secondary gfx.

I will then focus on getting the primary gfx (either onboard or pci-e)
to be passed through.
