Hello,
I ran into a problem here, where NetBSD wouldn't boot as Xen dom0.
I tracked it down to ACPI requesting a mapping to a memory area
no allocated to the dom0: the address is just above 4GB.
This looks wrong to me, because such adresss wouldn't work with i386 anyway.
The attached patch got NetBSD/Xen working for me, but with these messages:

hpet0 at acpi0: high precision event timer (mem 0xfed00000-0xfed00400)


There is a SATA controller in this system but disabled in BIOS,
which may explain the problem. Would this be a BIOS bug ?
Would there be a clean way to fix this ?
