for anyone interested,

upgrading openSUSE 11.2's kernel from 2.6.33-rc5-4-xen x86_64 ->
2.6.33-rc5-5-xen x86_64 fixed the problem reported here.  @ DomU, now,
 boots fine and the shared-bus PCI card is properly passedthrough.
dropping back to verify, and the problem returns.

the instructions @ wiki remain correct, and -- for kernel with pciback
compiled as module -- the command line options suggested (
xen-pciback.hide=(04:07.0)(04:06.0) pci=resource_alignment) do NOT
work.  rather the /etc/modprobe* config additions, along with the
usual (guestdev=0000:04:07.0,0000:04:06.0 reassign_resources) works as
it always has, consistente with the documentation.

hth.

thanks.
