This allows blkbk/netbk to load, but I guess a domU won't install yet.
xenguest-install fails with a panic in dom0.  I used this command:

    xenguest-install -n domu -r 1024 -f /root/domu.img \
    -l http://hummer.zko.hp.com/fedora/linux/core/development/ia64/os/ \
    -s 4 --nographics -p -x 'ide0=noprobe ide1=noprobe ide2=noprobe 
ide3=noprobe'

Here is the output on the dom0 console:
