The qemu-dm here is the qemu-xen-traditional, i.e. the legacy Xen fork
of qemu which uses ROMBIOS not SeaBIOS.

Hrm, this should either be provided by the Xen package (or maybe there
is a separate xen-qemu package?) or the Xen package should have been
patched to use the system qemu from /usr/bin. This is probably a
casualty of the upstream qemu-xen stuff being non-default in 4.2.x.

Does your /usr/bin/qemu-system-{i386,x86_64} link against any Xen
libraries? In which case you could try
device_model_override="/path/to/it"
