I don't think that this is very likely. The userbase is to small (right
now), not to talk about existing bugs that affect a larger user group
that won't be fixed.
Also Nvidia wants to see some extra $ for their premium products
(capable of Multi OS), I don't think they will just change the drivers
to make that feature available for every card.
If anyhow possible we should try to get that "intelligence" into
Xen/xen-qemu and not rely on the vendors. If tricky/untested/unstable it
should be marked as such and its usage made optional, but I see a lot of
potential in that direction.
Best regards,
Christian
