First of all, you have to verify that the packages you use are based on
XEN-unstable (I don't know the packages you mentioned).
Then you have to correct the grub boot entry to the following:

title XEN
    root (hd0,5)
    kernel /boot/xen.gz dom0_mem=262144
    module /boot/vmlinuz-xen root=/dev/hda6 vga=0x317 selinux=0
resume=/dev/hda2  splash=silent showopts pciback.hide=(02:01.0)(02:01.2)
(02:01.4)(02:03.0)(02:03.2)(02:03.4)(02:05.0)(02:05.2)(02:05.4)
    module /boot/initrd-xen

The pciback.hide is a Linux kernel parameter (not as in XEN 2.0.x).
And don't forget the matching pci = ... entry in the domU config file.

That should do the job (at least for me here).

Markus
