Aren't there problems in letting the guest OS driving somes IO by itself ?
Most of drivers have to deal with timings when speaking to peripherals.
What happens then if we or the host OS interrupt this drivers for others
tasks ?

That's an interesting thought. Of course most people won't want
to install extra hardware, but I'm sure there's a few that
would be into a double-headed video system; one for the
host, one for the guest.
If we added support to let the guest directly access
certain IO and memory mapped IO space, seems like we
could let the guest drive a 2nd video card on it's own.
