So, I never got to answer this. The answer is: eventually. When
we get to stabilizing 2.6.34 to work as Dom0, we will be definitely using
that.

For the DomU, if you feel adventurous, I've just updated two branches
with the latest Xen PCI frontend driver:
pv/merge.2.6.34
devel/merge.2.6.35-rc3
The 2.6.35-rc-3 contains the latest of the swiotlb, xen-swiotlb, xen
pcifront, etc. Lots of cleanup, merging of patches, etc. to make it
nicer for Linux Kernel Mailing List (LKML).
The outstanding bugs are:
- pvgrub isn't working well. If you specify 'iommu=soft' pvgrub breaks.
- the xen tools nor the xen pci front specify an PCI region, hence your
guess is limited to 3GB so that you have a memory region below 4GB
for 32bit guest devices.

Oh man, I like that. If you feel you have the time, booting the DomU
kernel with any hardware would be appreciated. And try to do funky
stuff. I don't think I've completely hardened the driver.
