So the initrd does get loaded and executed?
You gunzipped it manually?
(The problem with the initrd has been located meanwhile; after the
compressed initrd image, we attach the bootsplash screen data;
grub bails out on this.)
The tainting has been fixed: piix is now compiled in.

There's a 2.6.8-24.8 on
http://www.suse.de/~garloff/linux/xen/
Could you check whether this helps your problem?

Not good.

Something's wrong with the IDE driver.
Maybe some conflict between pci-ide and piix support.
Hopefully, the new kernel will help this.

Thanks for testing!
