Andrew is right. I used the sources listed there.

The domU seems to run fine so long as I don't push any high amount of data

It sounds rather like a bug that was fixed a long time ago in 2.6.18-xen and more recently in pvops dom0. But you'll need to talk to Gentoo to get support for those kernels; they are many steps removed from the Xen project.
