Hello Fred,
I have looked at your two dmesg outputs, from kernel-xen and kernel-smp.
There are two things that struck me.

from the kernel-smp dmesg:
> PDC20268: IDE controller at PCI slot 0000:06:05.0
> PDC20268: chipset revision 2
> PDC20268: ROM enabled at 0xfe8f8000
> PDC20268: 100% native mode on irq 26
>     ide2: BM-DMA at 0xc400-0xc407, BIOS settings: hde:pio, hdf:pio
>     ide3: BM-DMA at 0xc408-0xc40f, BIOS settings: hdg:pio, hdh:pio
> hde: ST3120026A, ATA DISK drive
> hdf: ST3120026A, ATA DISK drive
> ide2 at 0xcc00-0xcc07,0xc882 on irq 26
> hdg: ST3120026A, ATA DISK drive
> hdh: ST3120026A, ATA DISK drive

This didn't seem to be in the kernel-xen dmesg output.
I wonder if you are missing the kernel module for the
PDC20268 harware?

Looking in /lib/modules/2.6.11.4-21.9-xen/kernel/drivers/ide/pci
on my machine, I see two candidates, pdc202xx_new.ko and pdc202xx_old.ko
I don't know which one of those would work. Do you have either of these
loaded (lsmod)? You might need to put one of these modules in your
initrd maybe.

The other thing that struck me was the interrupts. The kernel-smp
seems to be using both ACPI and the IOAPIC hardware. The kernel-xen
doesn't seem to be doing that. Maybe the interrupt routing is broken
in the kernel-xen case. I am only speculating and I would not know
how to fix it in any case.

Hope that helps.
