Maybe the problem is on FreeBSD, and I'm not correctly clamping the e820
memory map returned by Xen. Right now I'm using start_info->nr_pages as
the number of valid RAM pages assigned to Dom0, but it is not clear if
start_info->nr_pages also takes into account the holes and invalid
regions in the e820 memory map.

This is the hw memory map reported by Xen:

(XEN) Xen-e820 RAM map:
(XEN)  0000000000000000 - 0000000000092400 (usable)
(XEN)  00000000000f0000 - 0000000000100000 (reserved)
(XEN)  0000000000100000 - 00000000dfdf9c00 (usable)
(XEN)  00000000dfdf9c00 - 00000000dfe4bc00 (ACPI NVS)
(XEN)  00000000dfe4bc00 - 00000000dfe4dc00 (ACPI data)
(XEN)  00000000dfe4dc00 - 00000000e0000000 (reserved)
(XEN)  00000000f8000000 - 00000000fd000000 (reserved)
(XEN)  00000000fe000000 - 00000000fed00400 (reserved)
(XEN)  00000000fee00000 - 00000000fef00000 (reserved)
(XEN)  00000000ffb00000 - 0000000100000000 (reserved)
(XEN)  0000000100000000 - 00000001a0000000 (usable)

And the Dom0 is assigned 1024M of RAM.

Roger.
