Given that there will be increasing levels of support for "pass-through"
hardware access in virtual machine environments and a trend in the direction
of virtualization-friendly hardware, we shouldn't preclude the possibility of
something a lot closer to syscons working inside of Xen in the future. This
means we should leave the syscons device names open so that syscons can claim
them if desired.
