We'll see if we can get some infos about this here...

Depends on the outcome of above, but effectively we would like to
not have the choice between "working or not", so ideally we can
just either fix it in QEMU or set the respective (working) option
for all new started VMs (QEMU machine versioned, to not break live
migration due to changed VM HW).
