Still seems very late, in i915 we kick out vgacon as pretty much the first
thing in driver load. See i915_kick_out_vgacon.
I wonder whether we should integrate that logic into
drm_fb_helper_remove_conflicting_pci_framebuffers, by checking whether

[PATCH] Paravirt framebuffer use xvc as console [4/5]
This is the patch from Amos Waterland for the xenconsole to
use /dev/xvc0 instead of taking over ttys. I''ve fixed a few places
which needed to check for XVC mode in addition to serial mode. Also,
until LANANA responds with an official minor, I''ve adjusted it to use
char 250/187 (in the experimental range) as opposed to 204/187.
(Should be identical to this patch from last

[RFC PATCH 00/35] Xen i386 paravirtualization support
Unlike full virtualization in which the virtual machine provides
the same platform interface as running natively on the hardware,
paravirtualization requires modification to the guest operating system
to work with the platform interface provided by the hypervisor.
Xen was designed with performance in mind. Calls to the hypervisor
are minimized, batched if necessary, and non-critical codepaths
