The DSDT cannot possibly come from anywhere other than hvmloader (as a
logic extension of Xen).  It is very hardware specific, including bits
of ACPI emulated by Xen itself.

There are plenty of improvements which can be made over the current
status quo by splitting out the optional parts into extra SSDTs, but
having the DSDT itself come from another source will cause all kinds of
problems for the domain.
