And now I tried the latest bits. 

I also applied Ian's legacy irq fix/patch. 

bootlog:
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-8-xen331-linux-2.6.29-rc3.txt

I guess I'll compile new kernel again with libata debug enabled.. 

Important parts of the dom0 kernel bootlog below.
