Yeah, if you do "make world" in the Xen 3.4.x source tree it'll download
linux-2.6.18-xen from the mercurial/hg repository during the build process.
You can install Xen 3.4.x like this without downloading/compiling the 2.6.18
kernel:
make xen
make tools
make stubdom
make install-xen
make install-tools
make install-stubdom
And then install/compile whatever dom0 kernel.
I recommend you to use either latest xen-3.4-testing.hg or latest
xen-unstable.hg,
and not the released Xen 3.4.2 because there has been a lot of VT-d related
fixes lately.

I'm not sure. linux-2.6.18-xen has some pf/vf drivers included, but those might
be only for the 82576 (1gig). Not sure though.
You might want to use the pv_ops dom0 kernel from Jeremy's xen.git 'xen/stable'
branch,
which is at version 2.6.32.9.
pv_ops dom0 kernel 2.6.32.9 requires Xen 3.4.3-rc 4.0.0-rc, it doesn't
boot/work with Xen 3.4.2.
