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.
