After reading some other, related posts on the xen-devel list I managed
to fix my problem.

I rebuilt my Xen with:
to force it to use the SeaBIOS provided by QEMU. Now the 'MMIO emulation'
errors are gone and the domU boots properly.

It seems the SeaBIOS used by default in the Xen build process is not
compatible with QEMU 1.7.1.

Now, I am going to prepare a separate package with SeaBIOS for my
distribution (PLD Linux) and make both QEMU (on runtime) and Xen (during
boot) use that.
