Hmmm... an upgrade to 2.6 code would be a non-trivial undertaking. But
Sven has got the 3ware controller working in vanilla 2.4.26.

I've updated our bootstrap ACPI code to code from the 2.4.26 tree -- it
looks like a bunch of additional parsing has been added in so, fingers
crossed, it may well make a difference. :-)  I also checked APIC,
IO-APIC, and PCI code but nothing there seems to have changed very
much. 

Sven: please pull the latest Xen and give it a go. If it still fails,
then send the new boot output from a Xen debug build, as you did
before. 

 Cheers,
 Keir
