 I had the same problems with this mainboard and I did not succeed in
getting the beta bios, too.

I managed to create a patch (attached) which hacks around some of the
problems and I succeeded in passing through PCI devices and the onboard
eSATA controller. VGA passthrough was impossible, maybe other PCIe
devices work / don't work. Integrated devices (USB controller, Audio)
didn't work either.

However, you have two possibilities:
- Try out the patch (was for XEN 4.0 hypervisor, should work on 4.0.1,
too) and test if the devices you want to pass through work
- Try to get a correct BIOS, there is a reference on the wiki page, but
it is not published on the internet and I didn't get it from the tech
support (but you should try that again, even if its only worth is to
express the interest in this technology to the mainboard developers).
