Let's see now.

Xen version: xen-hypervisor-4.0-i386 (4.0.1-4)
Kernel: 3.2+44~bpo60+1 (debian squeeze backport)

It was all installed using apt-get (eg. the package manager).

The system I have xen troubles with is a Dell PowerEdge 2600 (32-bit,
2 x 1 Xeon. no Intel Vt-d) with a via_sata controller and two sata

Intel IOMMU, doesn't that require Intel Vt-d?

Please let me know if there is more information I can provide.
