No, I was thinking more that if the xserver is not run by root, it
can't just have its way with the PCI resources. Then it can't wreak
havoc on what another xserver is doing with them, either. So, I think
that Tiago means that if the xserver is rootless, then it will
implicitly be accessing the hardware properly though the kernel and
will not interfere with another xserver trying to access the hardware.
