If the KMS drivers are modular then they're not going to end up running 
until you've hit userspace, at which point you've probably missed the 
initial messages. Even without you'll still need to wait for ACPI setup 
and PCI probing before getting anything. So you really need to use some 
other framework in order to get access to the framebuffer, and that's 
then going to have to be torn down and set up again when you move to the 
native driver.
